What safety precaution are to be taken for avoiding electric
An 8 pole, 50 Hz, 3-phase IM is loaded to a poing where pull
out torque will occur. The rotor resistance per phase is 0.3
ohm and motor stalls at 650 rpm. The slip when motor stalls

I'm generating a pulse of 3V with frequency 80Hz (12.5ms
time period) and pulse duration 0.125ms and feeding it to
a transformer since i want the pulse to get amplified
around 60V. At the output amplification s happening but the
pulse is changed to a spike, can you tell me what could be
(an ordinary transformer 220V-12V stepdown transformer is
reverse connected ie. now it is 12V-220V stepup and voltage
Can we use Motor protection CB while we use the VFD for
Speed control?? if not means please tell the reason!!!
What are the difference between CT/PT operated Meter and
RRAMR Meter for HT/LT application?
What do u understand voltage reg. of an alternator?
A powerplant has 8 gensets operating in grid parallel mode.
In one genset sometimes there is pf variation and kvar
variation. The plant operates in pf mode. When this
variation is observed the load is stable, voltage is also
stable, freq and genset speed is also stable. How will you
check the functioning of pf card. What shall be the ideal
output vdc of the pfc, from there it is input to AVR?
