We recently sent the rotor of our 2 MW AC brushless synchronous generator for rewinding, and the final testing/inspection is coming up. Can anyone tell me whats the test procedure for this purpose? What does one have to check during the testing? Any checklist?

Hi and welcome to the forum. Is it possible for you to contact the original manufacturer for their recommendations?

Hi Marky, I have been trying to contact the manufacturers but they have not yet responded. What are the general tests that we need to do apart from megger, hipot, impedence check etc?

sounds like you hit the big ones. 1) check impedance 2) check inductance 3) check balance. 4) you could check the B field strength at the poles, make sure they are at least consistent.
