A power transformer is usually employed for the purpose of converting power, from one voltage to another. If it is used for converting power from a high voltage to a low voltage, it is called a step-down transformer. The conversion efficiency of a power transformer is extremely high and almost …

what is armature winding? The winding from which you will get the output will be termed as armature winding . and the other winding will be called a field winding. Let me explain How? In case of D.c machines, we say that field winding is present on the stator field …

The lightning arrester protects the electrical equipment from lightning. It is placed very near to the equipment and when the lightning occurs the arrester diverts the high voltage wave of lightning to the ground. The selection of arrester depends on the various factors like voltage, current, reliability, etc. The lightning …

There are main three categories of insulator that is used as an overhead insulator: Pin Insulator Suspension Insulator Strain Insulator Pin Insulator Pin Insulator is one the youngest overhead insulator, that has a capacity up to 33 KV system. It has one part, two parts, and three parts type, which totally depends …

The motor is an electromechanical device, which consists of rotating conductors and magnetic field to transform electrical energy into mechanical torque. Whereas pump is a hydro-mechanical device that converts mechanical torque into hydraulic/pressure energy. Motoring action ( electric one ) obtained based on Faraday’s law of electromagnetic induction and motor …

A DC motor works in the same principle as an AC motor, with a mechanism to allow it to rotate even if the supply is not alternating. After all, simple motors work because the direction of current reverses (alternates) every half cycle, rendering the armature to rotate. Now, why does the …

A transformer is a device working on mutual inductance principle to convert electrical energy from one voltage/ current level to another. There are different types of transformers used for different purposes. (1) POWER TRANSFORMER Laminated core Transformer Toroidal Transformer Auto transformer Variable auto transformer Induction regulator Transformer(high voltage transformer) Polyphase transformer …

A contractor is an electromagnetic device which is used to make or break of an electrical circuit. there is two type of contractor. power contactor. auxiliary contactor. Power contactor is used in power circuit like switch on/off of a motor capacitor. while auxiliary contactor is used to switch on or off of a control circuit. a power contactor have 3 main contacts while an auxiliary contactor has many contacts like 1no+1nc 2no+2nc ect..power contactor is generally used where we required to make and break a large current carrying circuit. The Relay …

Here is some Basic Electrical Terms Full Form that Every Engineering Should know this:   1. HT = High Tension (Transformer HT Side) 2. LT = Low Tension 3. AB Switch = Air Break Switch 4. DO Fuse = Drop Out Fuse 5. ACB = Air Circuit Breaker 6. VCB = …

There are so many differences between these two by feature and application, however, few of them are as below: 1- MCB(Miniature Circuit Breaker) is for basic protection device to limit the current and fault in a circuit whereas ELCB(Earth Leakage Circuit Breaker) is advanced one which responds only when the …

The stator is an unmoving component of an electrical machine that’s going around the rotor. It’s derived from the word ‘’stationary’’ as the ‘’stator’’ implies. It contains the windings and provides mechanical support and protection for the motor.                             …

PLC is a Hardware to read the sensor (physical signal), solve the algorithm and gives the controlled output., whereas SCADA is the software which can be interfaced to PLC, to read and present the information in graphical, animated form or make a log. For example: Controlling the LEVEL is done by …

There are some basic formula of Electrical Engineering Formula Every Engineer Must Know this      

In This video, you will get how to test Big Ac Motor At Work Read More: Difference between PLC and SCADA

How inverters work. In this video, we take a look at how an inverter works to convert direct current (DC) into Alternating current (AC). Inverters are used increasingly throughout the industry as well as building services for HVAC systems to achieve precise control of AC induction motors connected to AHU …

In this video we learn how electricity works starting from the basics of the free electron in the atom, through conductors, voltage, current, resistors, led, to capacitors and transformers  Read More: How Does Transformer WORKS

In general way of common people’s understanding: These both words are used interchangeably by persons belonging to a different field than power electronics. They essentially mean to convey the functionality of the device (DC to variable freq AC) and as long as this is done, power electronics people (like me) …

Different Types of Sensors We live in a World of Sensors. You can find different types of Sensors in our homes, offices, cars etc. working to make our lives easier by turning on the lights by detecting our presence, adjusting the room temperature, detect smoke or fire, make us delicious …

Neutral Vs Earth Neutral : Neutral is the normal ” return ” wire. In systems where the load is supplied from only one Hot (or “Live”) wire, the Neutral completes the circuit and carries current back from the load to the power station. Neutral is a conductor that carries current …
