Dear Mr Abbas,

Your plant ambient is high you found several disturbance in your Gas Engine behavior also first you inspect your Gas Engine alternator G -3520 C installed with Neutral Isolation and your other Gas Engines Pitch matched with your G -3520 C Alternator. S econdly you measured the Neutral cable directly installed in your alternator proper rating and you monthly checked your grounding earh pits and take his ampers properly your running Power Factor matched with your running system and your power factor improvemnet plant run on auto On Off properly it is correct that you checked your detonation bar level and checked timing retard on D.D.T and corect your values if you find not proper if your engine not imrove his behavior so invite your engine dealer service department to adjust your engine behavior through adjustment tools as per O.E.M recommended procedures mention in your fault finding code book or instrument procdures book.
