1 4563i wasted one year for the job after completed my btech what can i say about 1year time in interview
2113A 50Hz,4-pole,3-phase,star-connected synchronous motor has a synchronous reactance of 12ohmsper phase and negligible armature resistances.the excitation is such as to give an open-circuit voltage of 13.2kilovolt.the motor is connected to 115kilovolt, 50hertz supplying. what maximum load can be the motor torque,line current and power factor?
2433IT IS DESIRABLE THAT THE INCOMING MACHINE SHOULD BE A LITTLE FAST AT THE TIME OF SYNCHRONIZING.EXPLAIN?

2261Can you used moeller lzm1 mccb in a dc system with 125vdc and 20ka short circuit current , beside is it have 24 or 48 volt shunt ? Beside how long current can through from An MCB shunt contacts? (like Z7-AS 24 V)?
2089why the voltage is in digit of 11/33/132/220/440 please send me on shukrerabbi_abkhalil@rediffmail.com with thanks

Define de-sensitivity?
Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????
