4 6340a 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 6679A 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.

1718How can transformer oil be used in transformers with voltage rating above its breakdown voltage?
2 3563why we still use sinusoidal waveforms for transmission and utilisation (we know generation is sinusoidal), instead of other ac waveforms such as triangle, sawtooth, square etc.,? is there any mathematical derivations to prove sinusoidal is efficient than others?

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
