I need to assume a power factor for a 4160V motor and for a 600V motor - what are acceptable values?

I am trying to spec a transformer for a quote and I'm not sure how to determine the primary and secondary BIL levels. Can someone help me out?

Thanks aolalde. I have another question. The client asked if end rush current would be an issue for the 600 volt motor. I usually work in controls so I don't even know what that means - can someone explain it to me and will it be an issue?

Thanks for the responses! I've been trying to figure what current each will draw and subsequently what size of cable will be required. I calculated (assumed efficiency of 80% and pf of .9): 600V: I = (500*746)/(1.732*600*.8*.9) = 498 A 4160: I = (500*746)/(1.732*4160*.8*.9) = 71.9 A Does...

I have a client who has a 600V supply and wants run a 500HP motor. They also want to know if it would be worth while to take their 13.8 kV service, step it down to 4160V and run the motor with that. I realize the cable will be smaller due to less current but is there any other benefits...
