OK,
SnTMan stated that the tube side can be exempted under U-1(f). U-1(f) addresses the pressure relief devices.
Can anyone help where it can be found in the code (July 2013 revision) ?
Thanks
Thanks mr.Waross for your contribution, what I was trying to point out is as follows:
There are two situation of out of phase synchronization; the generator ether leads or lags the grid. The synchronizing circuits differ, some circuits if you reverse two wires you will end up with an error of...
Hi all,
Sorry for the delay, I could not access any of the data, the case is under investigation by the OEM.
Mr.Pikoplatt
The IR values are in order before and after.
You mean by stator cables the termination? No it was not removed.
Generator Breaker: what do you mean by removing the...
Thanks for your thoughts
Out of phase closing, I have thought about this, will the out of phase closing cause a circulating current in the double winding of each phase?
Regarding GE, I would prefer to stay neutral in my opinion about all manufacturers...
And for the synchronizing scheme...
Dear David
This is not the first unit. 10 units are in-service without any problem.
And if it was setting problem how do you explain the Buchholze relay operation?
Posting the events… sure…but I think the osc.is better since it will show the currents and voltages waveforms. There was a severe...
Hello,
Background:
During a scheduled unit SD, the generator rotor was taken out and the stator goes under rewedging and retaining rings replacement process. In the mean while the old protection panel was replaced with a new numerical one.
Incident:
When we synchronized a 153MVA generator...
