Generator Rotor Barring Hrs

(OP)
Hi

Can someone please explain what effect will barring have on the rotor of 600 to 800 MW machine, will increasing or reducing the barring speed reduce the probability of fretting on the rotor slots etc?. With a two shifting station alot of our machines sees a lot of stop-start mode of operation hence increased barring periods.

RE: Generator Rotor Barring Hrs

Try googling "generator copper dusting"
