Large VFDS use premagnetising to limit inrush also this is sometimes used on weak systems but in your case it is not applicable.
Do a voltage dip calculation if you want to energize from the LV side.
Sounds as if you need some directional ground overcurrent relays which work off the capacitive current. Common
on ships and on hydrocarbon submersible pumps.
Thanks for the input.
Other than US it seems burn damage or death is largely ignored for LV manmade faults. Shell
are taking some retrofit and procedure changes in tankers. They are lucky because they have
always widely used fuses. Recent IEEE IAS article Mitigating Arc Flashes using IEC 61850...
