which one is rotating transformer-single phase induction motor or 3 phase squirrel cage motor?
1 4641i wasted one year for the job after completed my btech what can i say about 1year time in interview
2174A 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?
2528IT IS DESIRABLE THAT THE INCOMING MACHINE SHOULD BE A LITTLE FAST AT THE TIME OF SYNCHRONIZING.EXPLAIN?
1 3527WHEN TWO ALTERNATORS ARE OPERATING IN PARALLEL, EXPLAIN WHY IT IS OBJECTIONABLE TO OPERATE ONE AT A LEADING POWER FACTOR AND ONE AT THE Lagging power factor?
1 3868WHAT R THE SAFETIES IN A HIGH TENSION PANEL N LOW TENSION PANEL. ALSO WAT SAFETIES R THERE IN A 200 KVA TRANSFORMER?
2322Can 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)?
2141why the voltage is in digit of 11/33/132/220/440 please send me on shukrerabbi_abkhalil@rediffmail.com with thanks
