Induction Generator- Working, Torque -Speed Characteristic

An induction generator is also called an asynchronous generator. An induction machine can work as a generator. For working as a generator initially, the three-phase induction motor is started as a motor. During motoring operation, it draws reactive volt-amperes from…

Transformer Oil BDV Test and its Procedure

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…

What is Lightning Arrester-Working Principle Diagram

Grounding wire running over the tower or substation provides good protection to the electrical system against direct lightning stroke but they fail to provide protection against traveling high voltage or current waves that reach terminal equipment. The lightning arrester or…

Synchroscope Synchronizing

Function and Principles of Synchroscope Synchronizing A synchroscope is an essential device used for synchronizing AC power systems. It measures and displays the frequency difference and phase angle between two AC power sources. The device typically features a dial with…
