core type transformer is commonly used for power transmission

The gauge indicates the number of amps, but what about voltage? How voltage rating (for wire or fuse) determined?

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 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.

What, in the construction of a transformer, controls KVA? For example 600/208/120 V transformer can be 10kVA or 45kVA!!! What do we change in the construction of a Transformer in order to change the rating but not the voltage.
