In the Delta connection, the dissimilar terminals of three phase windings are connected together. The finishing end of one phase is joined to the starting end of the other phase to obtain mesh or delta-connected winding. Delta connection in the…
There are in general two types of transformer Shell type and core type transformer These two types differ from each other in the manner in which winding wound on the magnetic core. Core type Transformer In core type, the magnetic…
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…
Step down transformer is an essential component of many electrical systems. They are used to convert high voltage, low current power into low voltage, high current power. This is important because many devices and appliances require lower voltage than what…
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…
Three-phase induction motor also called an asynchronous motor is a widely used induction motor in the industry because it is cheaper, robust, efficient, and reliable. we are going to discuss the difference between Induction Motor and Synchronous Motor in this…
Voltage control is performed by changing the transformer turn ratio. This is achieved by providing Tapping on the transformer winding. In a tap changing transformer, taping is either provided on the primary or on the secondary winding of the transformer.…
The types of single phase induction motors are often classified by the names of the starting method used. Like Capacitor start Induction run motor (CSIR), Capacitor start capacitor run induction motor(CSCR), Permanent-split capacitor motor. A standard single-phase stator has two windings placed at an…
