The dielectric strength of transformer oil is known as BDV or break-down voltage. A Transformer Oil BDV test is performed to find the dielectric strength of transformer oil. BDV is the minimum voltage to withstand the capacity of transformer oil…
In the world of electrical, there are various devices introduced to protect both the electrical equipment and the personal operating it. Two of them are the Earth Leakage Circuit Breaker (ELCB) and the Residual Current Circuit Breaker (RCCB). While both…
Transformers play an important role in electrical power distribution and transmission systems, as they facilitate step-up and step-down voltage for distribution and transmission purposes. Because of its electricity to be transmitted efficiently. To protect transformers, various devices are fitted on…
Electric motors are used in a wide range of applications, from powering household appliances to driving industrial machinery. This guide will provide an overview of electric motors and their motor efficiency classes like IE1, IE2, IE3, and IE4. , as…
Brushless DC MOTORS (BLDC ) are an increasingly popular choice for many industrial and consumer applications. In this article we are going to discuss advantages and disadvantages of brushless dc motor. A brushless DC motor is a type of electric…
Definition: The ionization of air around the power conductor surface of the high voltage transmission line or the disruption of the dielectric strength of air near to conductor surface of the power line, producing hissing noise and causing a violet…
A single phase induction motor is very similar to a 3-phase squirrel cage induction motor but single phase induction motor is not self-starting.It has(i) a squirrel-cage rotor as similar to a 3-phase motor(ii) Single-phase induction motor stator has two windings…
Advantages of Direct current transmission compare to AC transmission Why we use HVDC transmission instead ac transmission? 1) HVDC Transmission can operate with one conductor and ground as return path.on other hand AC transmission required 2 or more conductor, Hence…
What is the power factor and power triangle? In the modern electrical distribution system, most of the loads are inductive in nature like motor,transformer, electrical furnace. when induction motor run on no load or light load, create lagging power…
Why Earthing/grounding testing is Necessary? Testing the quality of the Earthing system has been a critical part of any electrical system maintenance program. Ground electrodes provide a safe path to Earth for the dissipation of fault currents, lightning strikes, static…
