New Capacitor Banks for Mill Press Motors

Here are some examples of recent capacitor installations for drive motors.

Firstly, we have 2 22.3kVar ‘fixed’ C-Type PFC Units each connected to a 75kW 6-pole start/delta drive. These fixed style capacitor units work in line with the motor switching contactor so come into circuit whenever the motor comes online and then shuts off when the motor is stopped.

Another example of a 22.3kVAr PFC unit connected to a 75kW 6-pole soft start drive, this time mounted in its own enclosure incorporating a rapid discharge circuit and timer all controlled by the soft start 24V run signal few via a relay circuit.
