Answer / k.prakashchandra

If you want to measure ER of particular electrode ,you have
to disconnect it , to avoid the influence of other electrode
connected to the same equipment.If the cables are connected
in parallel ,the load sharing is inverse to the resistances
of cables so that the voltage drops in the cables are equal

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
