how will you calculate rated Primary and Secondary voltage and
Current for 2500 KVA, 11kv/443V Transformer

Answer Posted / rajutadhikari

Rated current on HV side:
Irhv = P/ (1.732 * V) = 2500k/ (1.732*11k) = 131.22 Amps

Rated current on LV side:
Irlv = P/ (1.732 * V) = 2500k/ (1.732*0.443k) = 3258.28 Amps

Is This Answer Correct ?    12 Yes 1 No
