Hi all,
In a substation in Europe we have a YD transformer with the neutral solidly earthed as per the picture below.
The transformer is a 155/66 kV 160 MVA.
How can I calculate the primary rating of the Neutral CT?
Thanks in advance for your help.

Details are as follows:
Both feeders are being fed from the same bus 33KV feeding each one one string of an offshore wind...
