Industrial Applications of Transformer

by

Industrial Applications of Transformer Q. Give industrial application of transformer. Transformer is such a important device used everywhere, where voltage from one value is to be changed to the other value. In generating stations to increase the voltage for transmission lines. In receiving stations, sub-stations to step down the voltage. In street light distribution. In … Read more

UPS Working Principle, Advantages, Application, UPS block Diagram

by

UPS full form :- Uninterruptible Power Supply UPS PARTS NAME AND FUNCTION. Rectifier The rectifier carries out several key functions. The first is to convert the input power from AC (Alternating Current) to DC (Direct Current). Its second main role is to recharge the batteries, while the DC power routes to the inverter too. Depending … Read more

Pulse Transformer Working, Important Parameters, Advantages and Application

by

Pulse Transformer For coupling square wave or a pulse from primary to secondary the conventional transformer need change of shape of signal. Pulse transformer is a transformer which is designed to couple pulses from primary to the load connected to secondary without changing the shape of the pulse. Pulse transformers are used for coupling pulses … Read more

High Frequency Transformers (Audio Frequency Transformer and Intermediate Frequency Transformer)

by

High Frequency Transformers In this category we study (1) Audio frequency (AF) transformer (2) Intermediate frequency (IF) transformer. (1) Audio Frequency (AF) Transformer Audio frequency range is 20 Hz to 20 kHz These transformers are especially designed for connecting different telephone systems to each other keeping their respective power supplies ‘isolated’. Following are the functions … Read more

Core Cross Section of Transformer and Yoke Cross Section of Transformer

by

Core Cross Section For small core type transformers simple rectangular section limbs with rectangular coils are used. However for large capacity transformers circular coils are used instead of rectangular coils, as a circle gives reduced length of mean turn (due to minimum perimeter for a particular area) which reduces requirement of conductor material, which in … Read more
