I have a new power transformer of 1 MVA (13.8 KV/400V) rating in Dyn11 configuration with neutral solidly grounded.All protections including ground fault protection is provided on the primary side. however presently the complete distribution set up at secondary side does not include ground fault protection at downstream. presently the system is being fed thru generators without the ground fault protection at the generator output (02 gen of 350 KVA each).
Now the secondary of the new transformer is protected thru overload and long time / short time overcurrent protection thru MCCB. introduction of ground fault protection can create tripping problems of the whole area due to any problem at downstream. what is the technical opinion for not using ground fault protection at transformer secondary???
An urgent response is expected please
