Answer
# 2
fault level depends on your system's percetage impedance.In
general practice we are using 28KA for 3 secs. or 40KA for
3 secs.

Mr. Ranjan is correct!!
Fault level of the system will depend on the system impedance.

for calculation of fault level, calculate the fault impedance and hence you can calculate fault current from system voltage and fault impedance. product of two gives fault level in VA (Generally specified in MVA)

What is TVSS Protection??? Emerson 2
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.   2
