HAI,I HAVE 6,60KW MOTOR FEEDERS IN MY MCC PANEL.HOW CAN I DO MY SETTINGS FOR OVERLOAD,SHORTCIRCUIT,GROUNGFAULT,INSTANTANEOUS TRIP FUNCTION IN MY 4000A CIRCUIT BREAKER?
1 3981I have 500A load (WHICH IS SEPARATE MDP PANEL),an MCC panel with 4000A Breaker.Already I have 2500A load.Can I connect this load directly to the Busbar since I have PROTECTION IN MY MDP Panel ?
4 8061During the troubleshooting of an inoperative shunt generator, you found the voltage to be 2+ volts; what is known from this. Is it (1). odds are the armature is good (2). odds are there is no field current flowing in field windings (3). odds are the armature is bad (4). both 1 & 2 are correct (5). both 2 & 3 are correct
2 6038We are having a 2000KVA DG set. It trips with Over speed and Engne Hot when the mahine is stopped in full speed. How shall I analyse the block load and reverse power.Is the problem related to power factor. The machine which runs on this DG is having all Synchronous motors with incividual Drives.

ONGC,
2386why various test are performed on electrical panels & power cables before commissioning on site & what are these test???
1997I have 2500KVA transformer delta/star,13.8KV/380V provided with LV 4000A breaker. Already I have 2300KW motor feeder with a full load 90%. Is it possible to connect another 1600A from that breaker? If so how the calculation is done?
3811sir please send me iocl written test paper in my e-mail account. i'll be obliged to you........ thank u roshan
