6 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 5064
power 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?5 5055
