i have applied for junior engineer 2 c&w for Guwahati RRB please send me last five year question paper
Good day everyone,currently in our premise we using 30kw slip ring motor with resistance bank which we use as forward and reverse at conveyor bar handling. So,my question is how do we calculate the resistance bank which is suit the motor. Kindly,assist me... thank you
In india, according to trade theory above 5 HP motor reqired star delta starter. But we R connect 11 KV motor with 14MW in Direct to line ( With VCB starter combination) Can U Guess, How it is possible ?????
why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?

5- What is the task (function) of the excitation and isolation transformers in power plant? 6- What is the task (function) of LCI (A), LCI (B) and LCI (COS) in power plant? : LCI (A) and LCI(B) are load commutating inverter for generator turbine starting. , LCI (COS) is load commutating inverter change over switch
pls tell us AC plant are how do work and parts name with picture
