Hi,
I've just got into my electrical engineering course and I need some help with a question of mine here.
During a site visit, we were shown a main LT panel which has switch gears, ammeters and different kinds of relays and the distribution network from that panel. In the main LT panel I've noted down the current readings as Ir - 163 A, Iy - 150 A and Ib - 147 A. The Line to Line voltage is 415 V at 50 Hz and Line to Neutral voltage is 230 V at 50 Hz.
From the above details, how would I calculate the kVA rating of transformer? The primary side voltage of the transformer is 11 kV and the secondary side voltage is 415 V and the frequency is 50 Hz.
