Answer Posted / amrinder singh rajomajra
The main adventage of using star-delta starter for
induction motors is as following-
if we start the motor with DOL(direct on line) or simple
starter the the motor requiers more current to start ,
which is 6-8 times the full load current.because the higher
tourqe is require to start the motor...
so in star-delta the motor is started in star, which
produce higher tourqe at lower current, means the starting
current is 4-5 times less than delta starting.
and then motor after start gets full speed and star
contecter is disconnect and motor runs in delta
connections.because torqe is less and lower current is
required.
