Answer Posted / md. m. u. noman
IN my traning preod i face this question.i have learn 2 mathod.
1st IR >= system voltage in M ohm +1 M ohm.
for example, 3.3kV motor IR= 3.3+1 =4.3M ohm....that means
greater or equel to 4.3M ohm..
2nd is IR >= (20*V)/(1000+2P)M ohm.(at 25 degree celcise)
where , V= rated voltage ofmotor;
p= power in kW......
