From the following info can anyone tell me how to work this out:
A balanced load draws a total power of 90 kw from a 400v three-phase system at unity power factor.
The load is supplied from a 11kv to 400v step-down transformer which has a delta primary & star secondary.
Calculate the line voltage, phase voltage, line current & phase current for both primary & secondary.
Any assistance greatly appreciated.
