LV Iron Core Motor Starting Reactors

Motor starting reactors are used to reduce the voltage during starting up of large 3 phase motors while at the same time limiting inrush currents.

Large motors generally draw 6-8 times more current than their nominal current from the grid. They are typically started with 70% of voltage and the rest of the voltage, while the other 30%, is dispersed across the motor starting reactor. After 15 - 20 seconds, the reactor is bypassed by contactors in the system.
