FINALLY UNVEILED THE ULTIMATE SECRECY OF PAGE RANK IMPROVEMENT FOR BLOG

How Unveil Ultimate Secrecy of Page Ranking

How You Unveil The Ultimate Secret Point To Improve the Page Rank Of Your Blog? 

get more traffic and your blog post will be hit by more visitorsBlogger, everyone desires to get a high page rank for his blog; a high page rank means Google includes all search engines like your website and makes it visible to much more visitors.  Ultimately, you will get more traffic and your blog post will be hit by more visitors.

Before unveiling the secrecy to get a high page rank for a blog, we would like to discuss the king rules of page rank for a blog or website. If we don’t know the scope or pre-condition of page rank for a website, may our work will go astray.


Some website contains huge potential to get good page rank, but not getting in just time due to lack of proper SEO (Search  Engine Optimization). Oppositely any website can not get a high page rank if does not contain quality content.

King Rules To Improve  Page Rank For Blog 

Before going to the king rules to improving the page rank of your Blog, remember-

“Don’t follow any model blindly, Be a model;
Someone may follow you”
You may see huge suggestions, lots of advertisements, and so many ways to get a high page rank instantly on your Blog. Yes, there are many ways to improve website page rank and that grows step by step; remember that’s not happened over a night! Also remember, one rule may work for me, but may not for you. So, you need your own study to find out the way to improve your website page rank; but there are some fundamental rules that work for all.


We already mentioned making quality content; yes, this is the first king rule. Without enough text content, you can not get a good page rank for your Blog.


Google will be your good friend and remember your blog to display in front of more visitors if you put a lot of unique informatics text that actually visitors are searching for. 


The second king rule for your Blog page rank is SEO (Search Engine Optimization) or search engine friendly blog. Actually, there is no shortcut way to optimize the blog for a good page rank. There are lots of factors to improve the page rank of a website.


This single post is not enough to describe the all factors that optimize the page rank. My personal opinion is that if we follow all the rules to optimize our posts for search engines then the article will be for the machine, not for humans! So,  here we will focus on some common and basic rules, but we will advise you to research yourself on your Blog which will help you to unveil the real page ranking factors.

What Technology Google Likes to Improve Page Ranking



Google including all other search engines have no time to read all of your content. You need to show Google some keywords from your post, Google just verifies your content and indexes to further remember.


Indexing your page, Google technology ultimately considers the following key points-


The page title and keywords;

Meta description of the page;

Contents text on pages ;

Link to other sources etc.


These points are very important to page ranking because Google has no time to scan all the page contents each searching time, Google just indexes the search keywords from these points and prioritizes relevant search contents.


When any user search for any content from any corner of the internet world, Google Spider search and compare the search keyword with each webpage and make visible to the user those pages which contain more relevant content. This happens within a few mili-seconds for Google.


The page title contains the most important keywords which actually means the contents of the pages shortly. The length of the page title will neither be very short, nor long. The standard length should be within 80 characters. Too long a page title may consider spamming!


Keywords and keyword phrases are important to page ranking, Google will not scan all the documents if find not any search keywords. First of all, Google searches the search keywords at the page title, and at the meta tag then consider source links. Ex- if you writing a post about cat food, the cat is the keyword. You should mention the word ‘cat’ in the page title, sub-title, post text contents, and in the meta tag; then your post will be visible when someone searches for cat-related something.


Meta Description, Google actually does not index meta keywords, it index meta description tag. The meta description should contain the most important search keywords. Meta description length should not excide 150 characters. More long or short and duplicate meta descriptions are shown as an error in webmaster tools.


Contents text on pages should contain the most relevant search keywords. Important keywords should contain in once H1 header, in multiple sub-header, minor-header, and body text.


Link to other sources on external or internal pages is very important to page ranking. Google values the sources of data and links to other pages. Backlink plays vital roles to earn a high page rank, we will discuss latter about backlink in this article.

How Open The Secret Door To Improve Blog Page Rank

Before we said there is no shortcut way to improve your Blog page rank, you should study and find out which step working for your blog. Now we will focus on some common ways that are helpful and proven to improve the page rank. We hope it will be helpful to you in opening the secrecy of your Blog page rank.

Quality and Unique Contents

We are repeating again, without improving the quality of your content you can not imagine the improved page rank for your Blog. Blog content must be good quality and unique. Yes, unique, you can not copy-paste the documents from others. Your content should have a unique special character. Original and useful content can give you a high page rank because visitors like useful content and Google likes to give a high page rank to the most visited page.

Keep in touch updating the website regularly

If you do not update your blog for a long time, your page rank may drop down. Every week you need to update and include some new content in your Blog, more frequently is better. Also, remember the contents you are putting, should match the described keywords, which will help to come back visitors and stay what Google also loves.

Optimize page contents

You posted quality writing on your pages, but may not be visible at the right time in the right place if your page is not optimized properly. The best way to optimize your content for conversational search, keep your post title with the most popular search keywords. Off course, the body contents of the article should fulfill the search query. Remember, over-optimization may cause for de-ranking of your page.

Image Optimize

Using ALT text on images, you can optimize and make Google searchable images. Google is blind and can not read the image, You need to introduce using some descriptive text in the “Alt text” box and give a suitable file name for the image.

Buildup a quality backlink

Google Like gives you a high page rank when to see visitors coming to your site from another site. Linking with other high page ranked sites you can improve your page rank easily. By sharing content,  adding links, and commenting on other blogs, you can buildup backlinks.

Sharing Contents

By sharing your blog content you can reach others very easily and firstly. Share your Blog by creating a site map, creating an RSS feed, translating your blog contents to other languages, sharing in many social networks, and sharing to other blogs there are so many ways to share. Also provide facilities to visitors to share their post with others easily, adding some social network buttons like Facebook, Google +, Twitter, LinkedIn, tumbler, Digg, Delicious, Diigo, StumbleUpon, Instapaper, Evernote, Pocket, Pinterest, etc.

Backlink Ultimately Improve the Blog Page Rank

Good quality backlinks mean other sites pursuing Google that your blog content is useful which Google appreciates to give you a high page rank. Ultimately huge quality backlinks alone can reach your Blog to a high page rank.

If you search on the net you will get 100 ways, maybe 200 ways to get backlinks. We are not going into more details, just chalking out some important link-building methods that are very simple and easy to all-


Introduce your blog to others' blogs by sharing, commenting, joining the dialogue, asking questions, giving suggestions, and many more conversations;


Submitting the blog URL to different search directories like Google, Yahoo, Bing, AOL, etc, you can earn huge benefits, especially if you are a new blogger.

Relays: LEXIS OF RELAY

What Is Relay? How Do Relay Work?

 Relay a device that opens or closes a contact when energized. Relays are most commonly used in power systems, where their function is to detect defective lines or apparatus or other abnormal or dangerous occurrences and to initiate appropriate control action. 

When the voltage or current in a relay exceeds the specified “pickup” value, the relay contact changes its position and causes an action in the circuit breaker. A decision is made based on the information from the measuring instruments and relayed to the trip coil of the breaker, hence the name “relay.” Other relays are used as switches to turn on or off equipment.

 
Relay Normally OFF Connection Diagram

If you look at these two figure, you will find the very first basic idea, how relay make automatic a circuit just using the control circuit.
Relay Normally ON Connection Diagram

Types of Relay

Relay is nothing but an open or closed switch, but for the purpose and place of used relay may be different types or named. Relay may be used in HVAC, Appliances, Security, Pool & Spa, Office Equipment, Telecommunications, Data-com, CP/OA, Office Automation, Process Control, Automotive, Energy Management Systems, Motor Drives/Controls, Appliance Controls, Industrial Control, Motors, Timers, Instrumentation, Test Equipment etc.

Normally used relays are as below:
Auxiliary Relay: a relay employed in power system protection schemes that does not directly sense fault presence and location. Typical auxiliary relays include lockout relays, reclosing relays, and circuit breaker anti-pump relays.
 
Bus Differential Relay a differential relay specifically designed to protect high power buses with multiple inputs.

Computer Relay a protective relay that digitizes the current and/or voltage signals and uses a microprocessor to condition the digitized signal and implement the operating logic.

Differential Relay a differential relay is a protective relay that measures current going into a device from all sources by means of a network of paralleled current transformers. Ideally, the operational current is zero for normal conditions, and rises to a high value (proportional to fault current) when a fault comes on inside the differential zone. Differential relays are commonly applied in bus protection, transformer protection, generator protection, and large motor protection.

Digital Relay a relay in which decisions are made by a digital computer, typically a microprocessor system.

Directional Overcurrent Relay an overcurrent relay that operates only for overcurrent flowing in the tripping direction. Direction sensing is typically done with respect to a voltage or current signal, which is not affected by fault location.

Directional Power Relay a protective relay that operates for power flow in a given direction. Applications are in cases where normal power flow is in one direction, including anti-motoring protection on a turbine generator and fault back-feed protection on parallel step-down transformers.

Distance Relay See impedance relay.

Electromechanical Relay a protective relay that uses electrical, magnetic, and mechanical circuits to implement the operating logic.

Fourier Optics Relay Lens a lens system that produces the exact Fourier transform of an image. Two such relay lens will reproduce an image without any phase curvature.

Frequency Relay a protective relay which monitors the frequency of the electric power system.


Generator Differential Relay a generator differential relay is a differential relay specifically designed for protection of electric power generators. Variations include allowances for split-phase winding machines.

Impedance Relay a protective relay that senses the operational impedance at a location, i.e., the ratio of voltage to current at any given time. During fault conditions on the protected line, the impedance relay will sense the impedance (distance in ohms) between the location of the relay and the fault.  Typical impedance relay characteristics are mho and reactance. Impedance relays are widely used in sensing phase faults on transmission lines. Ground impedance relays are available that measure the distance to a single phase to ground fault using a modified technique. Also known as distance relay.

Instantaneous Overcurrent Relay an overcurrent relay that operates with no intentional delay following sensing of a power frequency overcurrent, i.e., a current above its set point.

Lockout Relay an auxiliary relay which is operated by protective relay(s) that in turn opens the appropriate circuit breakers or other fault clearing devices. The lockout relay will remain in the trip position until manually reset, and is used in protective zones where temporary faults are unusual and the potential for equipment damage is high.

Loss-of-Field Relay a protection relay used to trip a synchronous generator when the excitation system is lost. Loss of excitation causes the generator to run as an induction generator drawing reactive power from the system. This can cause severe system voltage reductions and damage to stator due to excessive heating.

Master Control Relay (MCR) used in programmable logic controllers to secure entire programs, or just certain rungs of a program. An MCR will override any timer condition, whether it be time-on or time-off, and place all contacts in the program to a safe position whenever conditions warrant.

Negative Sequence Overcurrent Relay a protective relay that senses and operates on negative sequence overcurrent. Typical applications include the sensing of unbalanced faults and the protection of synchronous and induction machines from rotor overheating.

Out-of-Step Relay a protective relay that senses that a synchronous generator has pulled out of step, and is operating at a frequency different than the system frequency.

Overcurrent Relay a protective relay that operates when fed a current larger than its minimum pick-up value.

Overload Relay a device designed to detect and interrupt motor overload conditions. Motor overload relays may be actuated by thermal (temperature), magnetic (current), or electronic (voltage and current) sensors.

Overvoltage Relay a protective relay that operates on overvoltage.


Phase Comparison Relay a phase comparison relay is a protective relay used on transmission lines which operates by comparing phase angles of signals generated at opposite ends of the line. They employ a dedicated communications channel to make the comparison. The signals compared are typically corresponding phase currents or sequence currents.

Protective Relay a device that monitors the condition of the electric power system and determines the presence of faults or other system anomalies. The protective relay monitors current flow, voltage level, or other parameter. When it operates due to a fault or other event, it initiates a trip signal intended to open the appropriate circuit breaker(s) or other protective devices.

Sponsored:


Reclosing Relay an auxiliary relay that initiates circuit breaker closing in a set sequence following fault clearing. Reclosing relays are typically employed on overhead lines where a high proportion of the faults are temporary.

Residual Overcurrent Relay an overcurrent relay that is connected to sense residual current. Residual current is the sum of the three phase currents flowing in a current transformer secondary circuit, and is proportional to the zero sequence current flowing in the primary circuit at that point.

Seal-in Relay an auxiliary relay that remains energized through one of its own contacts, which bypasses the initiating circuit until de-energized by some other device.

Solid State Relay a protective relay that employs analog electronics, logic electronics and magnetics to implement the operating logic.

Sudden Pressure Relay a protective relay that senses the internal pressure in a transformer tank, and operates on sudden changes in this pressure. These sudden pressure changes reliably indicate a fault inside the tank.

Synchro-Check Relay a device used to monitor the frequency and phase angle of the voltages across an open circuit breaker. Synchro-check relays are commonly used to prevent breaker closing or reclosing on excessive voltage or frequency difference.

Synchronizing Relay a relay that monitors the voltage across an open circuit breaker to determine the frequency and phase relationship of the voltage sources on either side of the breaker. Synchronizing relays are used on generator breakers to bring the generator to the system frequency and to match the phase angle between the generator and system prior to closing the breaker.

Time Overcurrent (TOC) Relay an overcurrent relay that has intentional, selectable, time delay. The time delay is chosen so that the relay will operate more slowly than downstream relays or fuses, and more quickly than upstream relays or transformer fuses. Relay and fuse curves are generally displayed on time-current curves.

Time-Delay Relay relay that responds with an intentional time delay.

1. in control circuits, time-delay relays are used to cause a time delay in the state of the relay when power is applied or removed to the relay actuator;

 
2. in power system protective relays, the response time usually depends on the magnitude of the measured value. If the measured value is a large multiple of the pickup value, then the relay operates or trips after a short time delay. For normaler multiples of pickup, the relay trips after a longer time delay.



Transformer Differential Relay a differential relay specifically designed to protect transformers. In particular, transformer differential relays must deal with current transformer turns ratio error and transformer inrush and excitation current.

Under-frequency Relay a protection device that curtails loads in an area that is deficient in generation. Lower generation compared to load demands give rise to lower frequency and a frequency threshold can be used by the relay to initiate load shedding in order to balance generation and demand.

Under-voltage Relay a protective relay that operates on low voltage or loss of voltage.

Voltage Regulating Relay a voltage regulating relay senses RMS voltage level and issues commands to devices such as load tap changers, which then adjust the tap position to bring the voltage back to the desired level.

Relay Channel

a multi terminal channel in which the receiver observes the transmitted signal through two channels: one direct to the transmitter, the other via an intermediate transmitter/receiver pair.

Here in this article we would like to focus on general requirements and importance of various drawings, designs and calculation sheet to execute an underground power cable project.

The term “drawing” should also included here diagrams, schedules, performance curves, and calculations etc. required for the comprehensive design of the works. The Service Provider should be responsible for the provision of all drawings required for the various stages of the Contract to execute the project.

All drawings, apart from workshop drawings, should be submitted to the nominated Engineer for his approval, in accordance with an approved program. 

The Service Provider should ensure that drawings are submitted for approval in prior enough time such that they may be approved within the specified period by the Engineer, prior to manufacture or construction commencing. 

Further adequate time must be allowed by the Service Provider to permit any comments for revised or modification made by the Engineer to be incorporated.


Any works performed prior to approval of drawings by the Engineer will be entirely at the Service Provider’s own risk including any delays that may result from modifications being found to be necessary by the Engineer.

The numbers of drawings required and the method of issue should be mentioned  in flow diagrams to  specification that keep free from any confusion.

The Service Provider should be fully responsible for obtaining any drawing or data of existing plant and installations that he requires in order to carry out the works, and should also be responsible for verifying that any drawings of existing plant and installations are accurate.

The Service Provider should provide suitable drafting and other staff on site that he requires investigating and producing any drawings that he requires of existing equipment and installations in order to carry out the works.

Where existing installations have been modified or extended the Service Provider may  provide complete new sets of drawings. In this respect the Service Provider should provide drawings detailing both the existing and new works and may not limit the scope of the drawings to the new works only.

What Should be Format of Drawings and Calculation Sheet ?

How Follow Drawing Numbering and Revisions?

The Service Provider should be responsible for adding the nominated Engineers drawing numbers to all drawings prior to submittal. Following award of the contract the Engineer and Service Provider will review the numbering system, familiarize with each other requirements, and agree on the numbering system to be applied.

Comprehensive cross-reference are to be included on drawings and the Service Provider should include the Engineer’s drawing number in the cross-references.

At each and every issue of a drawing the revision should be raised, and details given in revision boxes on the drawings. Comprehensive details of revisions are to be given and phrases such as “REVISED”, “UPDATED”, “MODIFIED” or similar are not acceptable.

Reference to any drawing in communications should include the Engineer’s drawing number.

Drawing Submittals and Approvals Procedure

The Service Provider should submit drawings for the plant and works for formal approval to the nominated Engineer. A program of drawing submittal should be agreed with the Service Provider following the contract award. 

Drawings issued in accordance with this program should take account of the time periods necessary for postage, and approved by the Engineer, to ensure that approved drawings are available prior to manufacture the materials for the project execute. For site construction works, “Construction Issues” drawings are to be available, on site, at least 21 days prior to the commencement of the works.Where appropriate the drawings should be accompanied by supporting calculations.

Following examination the Engineer should allocate a status on drawings. The subsequent action and distribution of drawings will depend on the status given by the Engineer as detailed below.

“Approved”, the details of the drawing have been checked by the Engineer and appear to comply with the requirements of the specification. Once approved the Service Provider should raise the revision to indicate Approved by the Engineer on Mark the drawing “Construction Issue” and distribute as per employer requirement that mentioned in contract.

“Approved Subject to Comment”. The drawing has been examined by the Engineer, and apart from the minor details can be considered Approved subject to the Service Provider making the amendments required by the Engineer. The Service Provider may issue the drawing as “Approved” as outlined above without resubmitting to the Engineer for formal approval, provided the corrections have been made as required. 

“Examined and Returned with Comments”. The drawing is considered to be revised by the Service Provider and immediately resubmitted to the Engineer for approval. 

“Examination not required”. The drawing not requiring approval by the Engineer has been examined by the Engineer. Examples of typical drawings of this nature are: equipment schedules and diagrams of connections. Drawings returned to the Service Provider of this status should be stamped “For information only” and “Construction Issue” and issued in the same manner as Approved drawings.

Approval of a drawing by the Engineer must in no way to relieve the Service Provider of his responsibilities under the Contract.

Service Provider may revise a drawing for any reason following approval by the Engineer, the revised drawing is to be resubmitted for re-approval by the Engineer, the original approval automatically being void.

The Service Provider must submit,  marked-up copies of the drawing issue programmed indicating the up to date status on drawing submittal and approval on a monthly basis. In addition the Service Provider should submit a schedule of the total number of drawing submitted, together with the total numbers of each of the above categories. An “S” curve is also to be submitted indicating the total number of planned approved drawing together with the actual numbers to date.

As Built Recorded Drawing and Construction Amendment for Project

During construction of the Works on the site, the Service Provider should ensure that all departures, modifications and corrections to the approved drawings are recorded. All such changes to the drawings are to be marked in red to show on “as-built” stated and one set of “as-built” drawing are to be available on the site at all times.

If Service Provider wish to make modifications as per site requirement on the approved construction drawings which influence the operation of the Plant, he should obtain the approval of the Engineer’s representative prior to instituting the modifications.

Following examination of the “as-built” drawing the Engineer’s representative should return one copy to the Service Provider indicating approval of the construction modifications, or further modifications required to satisfy the requirements of the specifications.

Record Drawing for Cable Line Construction Project

On receipt of Approval of “as-built” drawings, the Service Provider  be responsible for the production of Record Drawings for the complete plant on each section of the Works.

The Service Provider should modify the revision to “As-Built” and “Record Drawing” for all drawings applicable to the section of the works and submit these for approval to the Engineer.

On receipt of the Engineer’s approval the Service Provider will provide sets of paper prints of each drawing as detailed on pre-specification of the contract. Any contract drawing included in the Operation and Maintenance manuals should also be revised in accordance with any “as-built” modifications and re-issued.

These sets of record drawings should be issued within 90 days of the Taking-over of the completed plant.
