Small Generator's are usually a low voltage or
highimpedance in case of HV generator with lower rating
hence the fault current will be less and equipments can
withstand the same. Where as in case of HV Generators with
larger ratings the voltage level is high or the impedance
is low hence the fault current is much higheer. In order to
limit the Fault current to the required level suitable
rating of resistance needs to be introduced between the
Generator neutral and Earth.

introduced between the Generator neutral and Earth and to
protect the insulation of the generator and getting heated
up while fault uccurs

I have a small system with two motors that are running on 380 vac, 60 hz. These motors are expensive and I usally get them from Brazil. I am adding another motor to the system, but I want to purchase a 480 vac, 60 hz motor to use. It will be on a VFD that is rated fro 380 thru 480. Is this posible and will I have to use a larger motor and derate it?
