Hyyy....
Here your phase volt is 6.3 kV means ur ngr side volt is 6.3 kv .
The fault current is 100 amp duering abnormal condition at ngr side..
So the resistance value is as below

R=V/I
R=6.3/100
=63ohm

I think this and will help u...


Otherwise give me ur email I'd I will send u the calculation description
