Hi,
I need to protect a 3,0 MW 11 k V electric motor. The 11 k V supply comes from a nearby power station, where a 11 k V cable is run to my 11 k V distribution panel, and the maximum earth fault current is limited to one amp at the power station. The protection relay I am using is limited to a minimum earth current of 20 amps. My question is : Is it technically possible to protect the motor againgst earth fault ?
Thanks.
