3 point starter is used for shunt and compound DC motor. it is called a three-point starter because it has three terminals named L, F, and A. The terminal named L must be connected to either side i.e the positive or negative side…
What Is Buchholz Relay? Buchholz relay is a mechanically operated relay that is used to protect the transformer from internal faults that occur inside the transformer tank like an inter-turn fault. Buchholz relay is an oil and gas-operated device. The…
This bridge was first introduced by Wheatstone for measuring the value of unknown resistance. Wheatstone bridge circuit consists of four resistors, two with known resistances P & Q and one known variable resistance R, and one unknown resistor X whose value…
Electrical safety is the main aim of any residential or commercial electrical installation. To prevent electrical shocks and identify insulation failures of electrical appliances, the ELCB full-form Earth Leakage Circuit Breaker is used. Generally available at different ratings 16A,32A, 40A,…
Single-phase salient pole synchronous motors are called reluctance motors. the stator of the reluctance motor has the main winding and the auxiliary winding the same as the single-phase induction motor. The motor starts as an induction motor. It is pulled…
In today’s word electric motors power everything. Among the most efficient and reliable options is the BLDC motor, or Brushless DC Motor. Also known as a brushless DC electric motor. Introduction to BLDC Motor A BLDC motor is a type…
WHAT IS AN ELECTRICAL LOAD? An electrical load on a power system is any electrical appliance that consumes electrical energy and converts it into heat or in other forms. Different electrical devices use electrical power to convert it into another…
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…
A fuse is a small wire connected between two terminals that are mounted on an Insulating base and connected in series with a circuit. A fuse is the simplest and cheapest current interrupting device used to protect equipment from overload…
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…
