When geneartor is running in poor lagging side power factor
its excitation current increases then it is running in
improved lagging side.Kindly tell me when gen is running in
leading side what will happen
Answer Posted / asif raza
MY DEAR FRIEND AS WE KNOW THAT, ALL GENERATOR ARE DESIGN TO PRODUCE THE POWER WITH LAGGING P.F,SUPPOSE IF WE INCREASE MORE EXCITATION CURRENT TO THE GENERATOR'S ROTOR FIELD, THE P.F WILL BECOMES LEADING & ARMATURE REACTION WILL TAKES PLACE DUE TO THE EFFECT OF STATOR FLUX ON ROTOR FIELD.SO YOUR AVR WILL LOSSES THE CONTROL OVER ALTERNATOR & YOUR WINDING WILL DAMAGE.
