If a motor of 8.5 KW with same load and using in both Star
& Delta one by one,then which will take more current in
star connected or in delta connected

Answer Posted / virendra

IF motor is started using a delta starter then VP=VL (
Phase voltage is equall to line voltage & Load current Isc
is become root3.Isc.

Now if this motor is connected in star then then VP=VL/root3
& IP= isc /roor3

It clearly shoow that in star connection motor take 1/3
times less current then starting in Delta.
