What is the working principle of induction machine? - How does the flux is induced in induction machine? - what is infinite bus? - If load is suddenly changed then what will change in infinite bus? - Why high voltage is considered in transmission

Question

Accepted Answer

Answers to questions related to induction machine and power transmission

Induction machine works on the principle of electromagnetic induction
Flux is induced in the rotor of the induction machine due to the rotating magnetic field produced by the stator
Infinite bus is a hypothetical bus with infinite power capacity and voltage
If load is suddenly changed in infinite bus, the voltage and frequency will change
High voltage is considered in transmission to reduce power losses due to resistance and increase efficiency

Accepted Answer

The electromagnetic induction is phenomenon in which the electromotive force induces across electrical conductor when it is placed in a rotating part of field.
When magnet moving near coil magnetic line cut and flux induced according to Faraday's law.
The bus whose voltage and frequency remain constant even after changing in load.
There is no more effect on infinite bus.
In transmission line we used high voltage because we keep loses in mind that's why voltage transmitted at high voltage. If u don't transmit at high voltage receiving end voltage is less then required voltage.
