Another way to limit motor starting current is a series reactor.
2.
Series reactors can also be used to limit fault currents.
3.
The plant consists of a General Electric BWR / 4 series reactor plant and a containment system.
4.
It can be seen that during a second stage with a series reactor, that during acceleration the motor voltage will rise as the line current drops.
5.
If an air core is used for the series reactor then a very efficient and reliable soft starter can be designed which is suitable for all types of 3 phase induction motor [ synchronous / asynchronous ] ranging from 25 kW 415 V to 30 MW 11 kV . Using an air core series reactor soft starter is very common practice for applications like pump, compressor, fan etc . Usually high starting torque applications do not use this method.
