NEC Rules for Conductors

The National Electrical Code (NEC) rules for conductors are primarily found in Article 310, which governs conductor sizing, insulation, ampacity, and installation requirements. These rules ensure safe and reliable wiring practices by specifying conductor types, allowable ampacities, marking requirements, and protection against overcurrent.

Electrical Substation Equipment: Circuit Breaker and Its Functions

A circuit breaker is an electrical switching device that automatically interrupts the flow of electric current in a circuit when it detects an overcurrent or a fault condition. It is designed to protect electrical circuits and connected devices from damage due to excessive current or short circuits.

The primary purpose of a circuit breaker is to prevent electrical fires and equipment damage that could occur if an excessive current flows through a circuit for an extended period. By interrupting the current flow, the circuit breaker stops the current from reaching dangerous levels and thereby protects the circuit and connected appliances or devices.

History of Wind Power Generation:

Wind power has been in use for serving mankind for centuries through what has been popularly known as “Windmills.” There is no “electrical” stage of energy in old-style uses where wind velocity is directly used for performing jobs such as wheat grinding, pumping water for irrigation, and sailing vessels etc. It enjoys the advantages of being plentiful, inexhaustible, renewable, and non-polluting, over and above being cheap for running costs. 

How Does A Simple Lightning Conductor Protect A Building?

How Does A Simple Lightning Conductor Protect A Building?

A lightning conductor, or Lightning rod, is a metal rod or wire that is fixed to an uncovered part of a building's roof or other tall structure to collect lightning and divert harmlessly into the ground.

Lightning conductor or Lightning rod is the same thing, in the UK people say Lightning conductor, on the other hand, US & AUS people call it Lightning rod.

What is the Leading Power Factor?

Power Factor 

In electrical engineering, the power factor measures how effectively electrical power is being used. It's a ratio of the real power (measured in watts) to the apparent power (measured in volt-amperes). A power factor can be leading, lagging, or unity.

The leading power factor occurs when the current leads the voltage. This usually happens when the load is capacitive, like in capacitor banks or certain types of lighting.

Having a leading power factor is often desirable for power systems because it can help counteract the effects of inductive loads, which usually cause a lagging power factor.
