Answer / pawanchauhan12
basically this type of problem created when motor winding delta coil sequence not proper. For finding of fault following this processor :- Firstly check motor winding continuity 1:5{RR} ,2:6{YY} & 4:3{BB} .if continuity not matched then interchanged sequence of {RR} wire of power .if problem not solved then again interchanged second sequence of {YY} wire of cable .

Answer / pramit dutta
By connecting the stator winding 1st in star and then in delta
,the line current drawn by motor at starting is reduced to 1/3 th as compared to starting current with the windings connected in delta.

Answer / naveen joshi
There are many reason whether resistance increased by terminal contact in motor or phase difference in roter and stator not matched during transition from star to delta , increase the pause timing in timer .
