to be adjusted.

Answer / arvind

all r correct parameters but one is not mentioned as polarity polarity of both d.g should be same or the alternators will burnt out they donot bunt recently as reverse diodes r placed between them they get first burnt if they not then alternator will get burnt

Answer / raghu

Need to be match voltage, PF,is same at the both the dg.

IN star -delta motors normally first operated in star mode {absulated given (r-y-b) phases after one miute change in delta mode in this case i am change phase sequience for example R -PHASE TO CHANGE Y-PHASE ;Y-PHASE TO CHANGE R-PHASE SO THIS TIME MOTOR WILL HAPPEN RUNNIG MODE EIGHTER(OR) STOP MODE(TRIP MODE)
