It is similar to the ground resistor calculation for transformer
The typical example was answered earlier for transformer dt.19-06-2009
Neutral of transformer can be grounded solidly earthed OR with Neutral Grounded with Resistance.
Typical shunt calculations fro 5 MAV 11/6.6 kv transformer neutral are as :_
Transformer rating = 5 MVA
Voltage ratio = 11/6.6 KV
Vector Group = Dyn11 (6.6 KV ground through Resistor)
During Earth fault voltage between Neutral
