Dear Sir,

We are running with 03 nos. of synchronous Generator(11kv) with following running parameters,

Machine Voltage = 11.100 KV

Excitation Current = 2.5 amps

Machine Current = 182 amps

Reactive Power = - 1.66 MVAr (negative reactive power)

Power factor = - 0.87 leading

Active Power = 3.06 MW

Generator Rating details,

Output - 7287 KVA, Duty - S1, Voltage - 11000V, Current - 383 amps, Power Factor - 0.8 lagging,

Excitor Rated current & voltage - 7.8 amps & 78.9 V

Generator protection relay having trip set point for under excitation protection Q< (40) is -2.16 MVAr with 2sec delay. 

Synchronous generators are running with leading Power factor with -1.66 MVAr reactive power, so what will be the consequences from generator health point of view.  What will be the risk. 

Pls share your comments pls.
