Why Capacitor and Capacitance are Used Electrical and Electronic Circuit?

Image
The Purpose of Capacitors Using in Electrical Circuit.Capacitor: Capacitor is an electrical or electronic device that used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator is known as capacitor.
Simply we can define, single or multiple conductors or metallic parts when placed in parallel then it form a capacitor. Capacitance: The effect or action of capacitance, or the behavior of capacitance is known as capacitance.


By definition of capacitance we can say, a capacitor is a passive two-terminal electronic component that stores electrical energy in an electric field and the effect of a capacitor is known as capacitance. 

The basic formula to calculate the capacitance of parallel plate capacitor is as below:



What is Different Types of Capacitors & Their Characteristics?
The most common kinds of capacitors as per named using dielectric materials and/or anode or cathode are: 

Ceramic capacitors have a ceramic dielectric; Film and paper capaci…

Smart Grid Technology and Application

Image
What is Smart Grid Technology?A smart grid is an electricity network which includes a variety of equipped and energy measures including smart meters, smart appliances, renewable energy resources, and energy efficiency resources based on digital technology that is used to supply electricity to consumers via two-way digital communication. The term smart-Grid also known as digital-grid that refers to the new digital technology or to modernize the electrical network grid.

How Smart Grid Uses in Electricity Network System?
The expression Smart-grid usually refers to a category of technology folk’s square measure exploitation to bring utility electricity delivery systems into the twenty first century, exploitation computer-based device and automation. 

These systems square measure created potential by two-way communication technology and PC process that has been used for many years in alternative industries. 

They’re getting down to be used on electricity networks, from the facility plants and…

TRANSMISSION AND DISTRIBUTION OF ELECTRICAL POWER EFFICIENT AND SMARTLY

Image
Transmission and Distribution of Electrical Power Efficient and Smartly.Considering the main parts of a typical Transmission & Distribution network, here are the average values of power losses at the different steps:
1-2% – Step-up transformer from generator to Transmission line
2-4% – Transmission line
1-2% – Step-down transformer from Transmission line to Distribution network
4-6% – Distribution network transformers and cables

The overall losses between the power plant and consumers is then in the range between 8 and 15%.
Except some isolated individual normal generation, most of national grid electricity is not used in the same place where it is generated. Meaning is that some individual normal scale generator may produce electricity for industrial, commercial or residential purposes where it used; but mass scale produced electricity actually generates far distance from consumer or city center.   Sense is that long-distance electrical transmission and distribution systems are necessa…

Why DC voltage is not Applied in Transformer Input

What Happen if DC Voltage is Apply to Transformer Input? Considering the importance we can say transformer is the most efficient electrical machine ever invented on the earth.
The main function of transformer to step up or step down the voltage to desired voltage level keeping the power level same at both primary and secondary or in simple input power and output power is equal.
So, we can define as a transformer  is a static device which convert electrical power from one circuit to another without changing its frequency and  it Steps up or Steps down the level of AC Voltage and Current.
Finally we draw the working principle of transformer that works on the principle of mutual induction of two coils or Faraday Law’s Of Electromagnetic induction.
When current in the primary coil of transformer is changed the flux linked to the transformer secondary coil also changes; hence an EMF is induced in the secondary coil due to Faraday law’s of electromagnetic induction.
Actually transformer is based …

How Can Convert Single Phase Power Into Three Phase?

Image
You may find there three options to convert the single phase power convert into three phase, such as-


static converter- using capacitor to create a power waveform;rotary converter- using connect single-phase motor to three-phase generator; electronic converter- using single-phase power converting into DC and then inverting into three-phase AC.

Converting Single Phase Power Into Three Phase: Using Digital ConverterHere in this article we will discuss and try to give very basic idea about converting the single phase power into three phase power in different practicable way. This is not the detail circuit diagram or shop design. This is the conceptual drawing that will help a beginner to start their project or enlarge their thinking about critical power supply.
 A digital phase converter actually creates a three phase from a single phase power  using a digital signal processor (DSP) or a electronic circuit what is used to control power electronic devices to generate a third phase of voltage…

OUTDOOR STRUCTURE FOR HIGH VOLTAGE POWER CABLE

Image
Outdoor Steel Structure Design and Installation for HV & EHV Power CableThe structures shall be designed to carry cable sealing ends, cables and cleats, earthing bars, earth disconnecting links, sunshields and other fittings  should be followed an adequate design manner.

Each sealing end should be provide with a separate structure which be positioned so as to align with the phase center distances of the substation equipment but not less than the minimum electrical and safety clearness as international standard like specified in BS 162.

All structures should be equipped with a suitable framework mounted immediately below the sealing ends to accommodate a phase plate in a conspicuous position. All phase plates shall be manufactured from mild steel sheet with vitreous enameled finish.

Don’t compromise to provide for fixing and bonding copper fittings as may be necessary to accommodate all apparatus affixed thereto and to secure the structures to their foundations. Factors of Safety on Ou…
