What is the d/f between DOL & star delta starter & automatic
star delta starter?
Answer Posted / cool
Whenever you start a big heavy electric motor, you need to
start it slowly to prevent the rotor overheating and
drawing an enormous current. When the windings of a 3-phase
motor are connected in STAR the current is reduced to only
root three of the normal running current that is taken when
it is connected in DELTA.

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
