This starter produces high efficiency and have the option to be adjusted to obtain the necessary torque and in accordance with the system.It very efficiency stater but the disadvantage is it very high cost to setup control panel stater.
It can improved torque ratio is achieved and starting current is typically 3 times Full Load Current , depending on the voltage taps selected.Typically it have taps at 50%,65% and 80% voltage.
During start-up, the motor is connected to the auto transformer’s tapping. This means that the motor starts up with a reduced voltage and a correspondingly low current.
