Myself Pranab Roy working in Alkamil Power, Oman. We have three GE frame 9E (125MW ) m/c., Recently we have faced a problem, the problem was: We have to shutdown the GT-1C, came in to turning gear at 99rpm but after 45min of running in turning gear jacking oil pump tripped due to single phasing (one of the phase got burnt). We have stopped the turning gear by making the module off, m/c came in to zero speed, in that case there is chance of rotor bowing . In GE frame 9E m/c , m/c remains at turning gear for 24hrs.
I want to know as a control room engineer in GE frame 9E m/c what we can do if Jacking oil pump tripped within 24hrs to prevent from rotor bowing.
Plz let me know i shall be thanfull if u do the needfull ,to know what are the steps we can do to prevent bowing.
Regards
Pranab Roy
