Winding insulation resistance checking of three-phase / single phase Motor The motor is mostly used machine to drive loads in the industry, for pumping, elevators, and conveyor belts. so its reliability must be maintained, for the long life of the…
The transformer is the main device of the transmission and distribution network hence its reliability is important in every aspect. The transformer must be able to deliver the required power to load. single transformer unit is used for distribution purposes…
How three-phase bridge rectifier work? Rectifier is a device that converts AC voltage into DC voltage. rectifier uses a diode and thyristor, to convert AC supply voltage into DC voltage. For economics of generation and transmission of power. The electric…
There are many electrical components are used in the electronic and electrical circuit like a resistor, inductor, diode, transformer, capacitor, and many more. without these electrical components, the circuit is incomplete. each part has a different function in the circuit.…
The term torque is meant turning or twisting movement of force about an axis. When dc machine is loaded either as dc motor or as a generator. the rotor conductors carry current, these conductors are in the magnetic field of…
There is a wide range of applications of induction motor in Industry as well as in daily life. because of its simple design, rugged construction, and reliable operation. induction motors have easy operation and simple maintenance, low initial cost, high…
Induction motor is mostly used motor in the industry as well as in domestic application because it’s a simple design, reliable operation, rugged construction, and simple control gear for starting, speed control, and three phase induction motor braking like plugging, dynamic…
How to test relay? Methods for testing electric relay A relay is defined as an electrically controlled device that opens and closes electrical contacts with the help of electromagnetic switching and performs ON and OFF operations of other devices in…
Transformers are said to be connected in parallel operation when their primary connected to a common supply and secondary connected to a common load. The function of the transformer is to deliver power to the locality, city. But in some cases, a…
The transformer is the main device of the power system and its reliability is more important. Hence protection must be provided to the transformer. Buchholz relay is used to provide protection to the transformer against fault that occurs inside the…
