usually the power cables are used at the high voltage side
called as High Tension side. similarly on low voltage side
called as Low tension.
But in a transformer HT stands for High Temperature and LT
stands for Low Temperature.
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 switchgears, 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 - 163A, Iy - 150A and Ib - 147A. The Line to Line voltage is 415 V at 50 Hz and Line to Neutral voltage is 230V 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 415V and the frequency is 50 Hz.
