Why we use less dia. fuse and conductors at H.T. side, although we use higher dia. cables on L.t. side?
RRB,
4 7929a 650 KVA diesel generator is 1500 rpm, voltage is 415V n full load amps is 805 something,when are applied load more than 400 amps it's voltage is dropping, what is the reasons...?
4 8037A TRANSFORMER 440/400V,DELTA/STAR CONNECTED.THE NEUTRAL CONNECTED WITH GROUND CABLE THAT IS DIRECTLY CONNECTED TO THE PANEL,FROM PANEL IT IS CONNECTED EARTH PIT.IS IT RIGHT? IF IT IS RIGHT LEAKAGE CURRENT AFFECTED.SECONDATY IS PROTECTED WITH EARTH LEAKAGE RELAY.
