Ferranti Effect in Transmission Lines: What is it?

What is Ferranti Effect? The Ferranti effect is a phenomenon that describes the increase in voltage that occurs at the receiving end of a long transmission line relative to the voltage at the sending end. The Ferranti effect is more prevalent when the load is very small, or no load is connected (i.e

What is Power Factor: Improvement, Formula And Definition

What is Power Factor? In electrical engineering, the power factor (PF) of an AC electrical power system is defined as the ratio of working power (measured in kilowatts, kW) absorbed by the load to the apparent power (measured in kilovolt amperes, kVA) flowing through the circuit. Power factor is a d

Power Factor Correction: What is it? (Formula, Circuit And Capacitor Banks)

What is Power Factor Correction? Power factor correction (also known as PFC or Power Factor Improvement) is defined as a technique used to improve the power factor of AC circuits by reducing the reactive power present in the circuit. Power factor correction techniques aim to increase the efficiency

Understanding Skin Effect in Transmission Lines

A transmission line is a conductor that carries electrical power or signals from one point to another. Transmission lines can be made of different materials, shapes, and sizes, depending on the application and the distance involved. However, when transmission lines are used for alternating current (

Types of Overhead Conductor

Conductor is a physical medium to carry electrical energy form one place to other. It is an important component of overhead and underground electrical transmission and distribution systems. The choice of conductor depends on the cost and efficiency. An ideal conductor has following features. It has

Conductor Resistance Test of Electrical Power Cables

This test is used to determine the DC resistance of copper or aluminum conductors . Resistance of a conductor tells us how easily a conductor allows the flow of current through it. Higher the resistance, lesser the current will flow though the conductor. Resistance of a conductor is influenced by co

Wrapping Test for Conductors

This test is done on aluminum wire used as conductor in power cables to determine its ductility. Ductility of a conductor is nothing but the property of how easily it can be wound and twisted. Higher the ductility, easily the material can be wound and twisted without its breaking. This property play

Annealing Test for Wires and Conductors

This test is normally carried on annealed copper wires, aluminum wires for welding cables and solid conductors of electric power cables. The current carrier conductors of power cable is subjected to twist and bend during laying and installation hence it should be flexible enough to take any desired
