In one of my projects we were feeding the entire plant by means of 3MVA, 6.6kV,Dyn11 Transformer. This Transformer is Resistor Grounded ie., Neutral Grounding Resistor (NGR)for which a we have provided Netural Monitoring Relay (NMR). Inside the NMR there is a sensing Resistor which is of rating 5kV, if we change the rating of sensing resistor to 15kV is there any problem w.r.t operation of the NMR. Please guide me in this regards.
