Answer / jawahar
when we come to apparent power it denotes as kva ..if my power is upto 25 kv , then p= v*i for single phase ( 230volts)..if my power is above 25 kv then p= root3*v*i..(3phase 425 volts)

Answer / manoj kumar sharma / sunil kum
LT Side Voltage/HT Side Voltage= HT Side Current/LT Side Current
Exp.:- LT Side Current find out[Ip]=Vs*Is/Vp,
HT Side current find out[Is]=Vp*Ip/Vs

Answer / kk
Its depend on ct ratio of plant switch yard. For example 100/5 ct ratio so if ht current is 50 than lt current is 50×20=1000

Answer / dnyaneshwar
HT. P=√3 VI. In HT Supply vtg in Delta v=vph
LT P=√3 VI COS¢ consider ( V =√3Vph bcs LT side vtg will be in Star connection v=√3Vph
