We operate a 10 Mw facility and we have been experiencing
several trips due to fluctuations on the MVAR? We have
checked all issues related to the AVR and we have found all
OK? Can anyone help us? The grid voltage, internal voltage,
all regular parameters look ok. MVAR fluctuate and there it
goes the unit? What could be happening? Thanks!

Answer Posted / naresh

this could be because of the interturn winding losses that
takes place in the lines.this factor may increase the MVAR
rating of the system,which infuence the performance of thea
system.
