(combined CR 260 A, FC 590 A)or 6x 18 SWG (CR 270 A ,FC
616A) The currents in HT is 10.5A and LT 267 A f0r 200 KVA
Tr.CR=current rating,FC= fusing current

Answer / nirmit

Just Forgot HT LT here i give formula for amp

If 66000v KVA/114180*1000= found amp
11000v kva/19030*1000
440v kva/717.95
how

kva=route3*v*i
1.73*66000*i
114180*i
2000=114180*i
i=2000/114180
=0.0175*1000
=17.15 amp at 66000v
