Generator RTD
Generator RTD
(OP)
I have installed 12 RTD on the 133 Mw Generator stator winding, 4 for each phase. At the time, we have 4 damage. There`s another way to get a realistic value of the winding temperature, by other electric parameters calc???.
Im afraid that we must open the generator, and take off the RTD damage from the slot.

RE: Generator RTD
You may be able to come up with your own little formula for calculated the winding temp using your good RTDS and the current in that phase. This is the only way I know to figure out winding temp without actually measuring it.

Does the generator also have H2 field cooling? If so a pyrite "smoke" detector would detect damage is occurring from a hot spot and used to alarm/trip.

Additional to this RTD, we also have the Stator teeht temperature (2 lectures), Stator Core temperature (4 lectures), and the temperature of the air inlet/outlet for coolinf for each side (Non driven, driven side).
The problem is that the generator could lost more RTD signal, and we won`t know the temperature of the winding. In case of a temp increase, how to avoid any problem. We used to down the reactive load, but in a dangerous case, we would down the active power.
Also i did a thermal scan, but it isn`t continue like the RTD. I want to know if exist alternatives like a formula to calculate a avg temp for a given load of the generator.
Thanks for ur help
