It is important that the break between the Star contractor switch OFF and the Delta contactor switch is ON because the Star contactor must be reliably quenched before the Delta contactor is activated. During the transition period of switch-over, the motor must be free running with little deceleration. It is also important that the switch over …
Star and Delta Connection are the two types of connections in a 3 – phase circuits. A Star Connection is a 4 – wire system and a Delta Connection is a 3 – wire system. Before going in to details of the Star Connection, Delta Connection and comparing those two, let us have a very brief note on three – phase electric power.
