how calculation to be done of cable size/o.h. conductor size of 11kv h.t.for the load of 2175 kw
1 71936 MVA transformer secondary is rated for 725V at no load. The incommer ACB is rated at 690 V, 3200 Amp. Would there be any effect on performance of ACB due to lower voltage rating?
5 9247power is the product of voltage and current.so we can measure the value of power just by using ammeter and voltmeter.......then why do we use a wattmeter?

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened. Why does the strand conductor of Electrical power transmission line make twist?
