Critical Disruptive Voltage is defined as the voltage level at which complete disruption of dielectric strength of air surrounding the conductor occurs. If the voltage further rise above critical disruptive voltage Corona starts occurring. The air around the conductor has…
Electrical equipment that is connected to the power system and consumes electrical power is known as an electrical load. electrical loads are classified into three types that are resistive loads, capacitive loads, and inductive loads. they are differentiated from each…
Star delta starter is a very common type of starter and usually use to start a three-phase induction motor. Star delta starter also called a Y-delta starter is used for squirrel cage motors that are designed to run normally on…
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…
The BDV test, which stands for breakdown voltage, is one of the most important test to find out dielectric strength when it comes to transformer oil. BDV show’s the minimum voltage withstand capacity of transformer oil without breakdown. It is…
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…
Universal motors are electric motors that can be driven by either AC or DC electricity. in this article, we are going to see the Advantages and disadvantages of universal motors. They are also known as series-wound motors and are used…
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…
Testing of Three Phase Induction motor after manufacture or after installation on site are made in accordance with standard Specifications. Routine testing of induction motor Further tests on particular types of induction motor (e.g. commutation, starting) are required to obtain…
