A LT ckt i mean 440 volt flow of current100A.at this time HT current what will ON 11 KV &33 KV.plz givemy answer with example

Answer Posted / saraz06a0222

If KVA is known then these are the formulas

Current in LT side
=KVA *1000/1.732*LT VOLTAGE*COSQ


Current in HT side
= KVA *1000/1.732*HT VOLTAGE*COSQ

Is This Answer Correct ?    0 Yes 2 No
