There is no hard and fast rule connecting power rating and design voltage. The primary side of a 5500 kW distribution transformer in India will likely be at least 11kV and that of a 500kW unit 6.6 kV.
Voltage = Watts/Amperes
Voltage = Watts/Amperes
Volts*Amps = Watts (well, not exactly, the correct answer is VoltAmps, only part of it is Watts and the fraction is called power factor)
What will be the voltage of 500 kilowatt, Can you please tell me the rules of kilowatt to voltage. Thank you, Regards - Amit Mallick, Kolkata.
