What is a superconductor? 

We want to know how superconductors work and what a superconductor material is. The material that achieves the superconductivity property is known as a superconductor. Now, the question is, what is the superconductivity property? How can a material achieve the superconductivity property?

This phenomenon was first discovered in 1911 by Heike Kamerlingh Onnes, and it has since led to various technological advancements and applications.

Magnetic Hysteresis

What is Magnetic Hysteresis?

Magnetic hysteresis is a phenomenon observed in ferromagnetic materials, which are materials that can be easily magnetized. When a ferromagnetic material is subjected to a changing magnetic field, such as the alternating current in a transformer or the changing magnetic field in a magnetic circuit, the magnetic properties of the material exhibit a lag or delay in response.

What Are Corona's effects on electrical energy transmission lines?

If you look along the high voltage power transmission line in a clear sky at night, you will observe the dreamiest violet glow phenomenon embedded with hissing noise along the transmission line conductors. This indefinable phenomenon causes nothing but a production of ozone gas surrounding overhead electrical energy transmission lines known as the Corona or Corona effect.

You can also combine series and parallel wiring to achieve the desired impedance, which will be explained further below.

impedance refers to the load a speaker places on the amplifier.

Capacitance and Capacitor Must Know Electrical Engineer

A capacitor is an electronic component designed to store and release electrical energy in a circuit. It consists of two conductive plates separated by an insulating material, known as the dielectric. The primary property associated with capacitors is capacitance, which is a measure of the ability of the capacitor to store charge. Capacitance is typically denoted by the symbol "C" and is measured in farads (F).

When a voltage is applied across the plates of a capacitor, it creates an electric field, causing positive charges to accumulate on one plate and negative charges on the other. This charge separation results in the storage of electrical potential energy. The greater the surface area of the plates and the closer they are together, the higher the capacitance.

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.

 

How Vibration Damper Works in Transmission Line?

How Does a Small Size Damper Reduce Vibration in Transmission Lines?

Vibration dampers are usually used in high voltage and extra-high voltage electrical energy overhead transmission lines to handle aeolian and galloping or dancing vibrations in the transmission lines' conductors. The dampers are designed in such a way that they attenuate the line vibrations by reaching the same frequency as the cable that has wind-induced vibrations.

The overhead Transmission Line mainly experiences two types of vibrations in a vertical plane which can be categorized into two groups.

• Aeolian Vibration;
• Galloping or Dancing vibration.

Calculating the Resistance of a Wire

In many cases, we will know the length of a wire l and the AWG (American Wire Gauge) or SWG (British Standard Wire Gauge) or IEC standard size of the wire, but not the resistance. It's easy to calculate the resistance though.

Wikipedia has a list of AWG specifications available here, which includes the resistance per meter in Ohms per kilometer or milli Ohms per meter. They also have it per kilofeet or feet.

Electromagnetic Induction

Electromagnetic induction is a phenomenon in physics where a changing magnetic field induces an electromotive force (EMF) or voltage in a conductor. This principle was first discovered by Michael Faraday in 1831 and later formulated by him and Joseph Henry.

The key points of electromagnetic induction include:

Faraday's Law of Electromagnetic Induction:

Magnetism and Electromagnetism

Permeability is a fundamental property that characterizes a medium's ability to allow the flow of a substance, typically fluid, through it. Two essential types of permeabilities—absolute and relative—play crucial roles in understanding and analyzing the transport of fluids in different materials. 

Absolute permeability refers to the intrinsic ability of a medium to transmit fluid under a specific set of conditions, often measured in units such as darcies. It is an inherent property that depends on the medium's internal structure, porosity, and connectivity between its pores or fractures.

Electrostatics and Most Related Theory

Electrostatics is a branch of physics that explores the study of stationary electric charges and their interactions. It deals with the behavior of electric charges at rest, investigating phenomena such as electric fields, potential differences, and the forces that arise between charged objects. At the heart of electrostatics is Coulomb's Law, which quantifies the force between two point charges and highlights the inverse square relationship between the distance separating them. 

The fundamental concept of electric charge, whether positive or negative, forms the basis for understanding the intricate workings of electrostatic phenomena. 

DC Network Theorems

 Kirchhoff’s Laws: Kirchoff's Law means Kirchoff's current law and Kirchoff's voltage law, measuring the total current and total voltage accordingly.

Kirchhoff's Current Law (KCL): 

The total current entering a junction is equal to the total current leaving the junction.
Kirchhoff's Voltage Law (KVL): 

The total voltage around any closed loop in a circuit is equal to the sum of the voltage drops.

Electric Current and Ohm’s Law

Electric current and Ohm's law is very much essential parts of knowing as an electrical engineer.  I'll provide brief explanations for each term:

Electron Drift Velocity:

The average velocity of electrons in a conductor in response to an electric field.

Charge Velocity and Velocity of Field Propagation:

Charge velocity refers to the movement of electric charge, typically electrons. The velocity of field propagation is the speed at which changes in the electric field travel through a medium.

Renew Electrical Work, Power and Energy

Electrical work, power, and energy are fundamental concepts within the realm of electrical engineering and physics, playing a crucial role in our modern technological society. Electrical work refers to the transfer of energy through the flow of electric charge, typically achieved by moving electrons through a conductor. This flow of charge is harnessed to perform various tasks, from powering household appliances to driving complex industrial machinery.

Power, in the context of electricity, is the rate at which work is done or energy is transferred. It is measured in watts and determines how quickly electrical energy is converted into other forms, such as mechanical, thermal, or light energy. Understanding power is essential in designing efficient electrical systems and ensuring they meet the demands of different applications.
