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 2123
I 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 4533
During 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 correct2 3013
We 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.1 1799

What is meant by load angle of an alternator? Upon what factors does the load angle depend?
in general it is observed in power stations, the tertiary winding is used in higher rating Y-Y auto transformer but not in Y-Y power transformer. is the tertiary winding is compulsory then why it is not using in power transformer
does not the circulating current in a transformer affect the flux distribution in the transformer core
