Different Transformer Testing | Electrical Engineering Darwaza

transformer testing

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 …

Difference Between Pump and Motor | Electrical Engineering

motor vs pump

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 …

Difference between a Contactor and a Relay | Electrical Darwaza

contactor vs relay

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 …

How Inverters Work – Working principle

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 …
