In our plant We have MV 11KV power generation with NER of 40 Amps on each and 11/0.4 KV MV/LV trafo solidly grounded . We have earth grid through out our facility to sustain calculated short circuit current at each location. Have resistance of 2-5 ohm nearly at each point of 4sq KM facility for...
Generator of 400 V 1250 KVA shows Max 3 Phase Short circuit current of 19 KA . In my opinion it is the maximum three phase SKA that Generator can produce obviously can produce higher P-G fault being solid ground.
We have 3 Generators in parallel.
My question and confusion is that when we model...
