My system is 22kv/3.3kv transformer. client is asking to use
NGR, but as we have dedicated Neutral Earthing systems which
has a value less than 1 Ohm. So i want solid comparision.
Why i should not use NGR as my system is already
protected.Can any one help me to get out of this.how should
i reply on basis of some great comparision and calculations.
Please help
