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)
Answer Posted / sundaresan044
STOP AND TRIP It will running in the opposite direction.Once we change the Phase motor running in oppsite direction only
