Generator Temperature Rise Test

[FONT="]Generator Temperature Rise Test[/FONT]


From a few days, we have made a test on the Generator’s windings (Stator and Rotor), this test accomplish the temperature rise of the windings at full load is within the Normal range.
First, we increased the load to full load (350 MW), then increased the reactive power and the terminal voltage at about (19.7 KV).


1) Procedure for stator winding.
-Apply the following formulae, after you collect the data every 30 minutes.


Ts = ( Tst – Ts1 ) * ( In / Ib )2 + Ts1


Tst = Actual stator winding temp. – Avg. cold gas temp
Ts1= Factory test value = 4.4
In = Factory test value = 13.37
Ib = Max. Current value






2) Procedure for rotor winding.
-Apply the following formulae, after you collect the data every 30 minutes.


Tf = Tft * ( Ifn / Ift )2


Tft = Actual rotor winding temp. – Avg. cold gas temp
Ifn = Factory test value = 2945
Ift = Actual Current value




Ts and Tf , should be at the normal levels , at full load
