Types of insulation classes used in electrical motor/ transformer There are three main categories of insulating materials, gases, liquids, and solids. The types of insulating materials are classified mainly based on thermal capability. types of insulation classes for electric motors…
Double Revolving Field Theory The double field revolving theory of single phase induction motor is proposed to explain this problem of no torque developed at starting and yet torque once rotated. Double revolving field theory is based on the fact…
Classification of power system Buses In the power system, every bus is associated with four different quantities, real power, reactive power, bus voltage, and phase angle. In load flow, two parameters out of the four are specified and the remaining two…
While selecting an induction motor, Motor Duty Cycle must be considered to meet the induction motor application requirement. The duty types are indicated on motor nameplate data by S1, S2… In the absence of an indication of the rated duty…
All electrical devices run on electrical power, the consumed energy is measured in terms of watts. the device used to measure consumed power is called a watt meter. to measure three-phase power mainly two methods are used namely two wattmeter…
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…
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…
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…
TNC switch stands for Trip Neutral and Close. TNC switch has three positions and it is used to operate the circuit breaker locally. TNC Diagram In this article, we will discuss the working purpose and function of TNC in electrical…
The ANSI code for the trip circuit supervision relay is 95. supervision relay plays an important role in ensuring the reliable operation of circuit breakers. 95 TCS relay continuously monitors the healthiness of the trip circuit and gives an alarm…
