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
