POWER FACTOR CONTROLLERS

The capacitor banks are equipped with a digital power factor controller. The controller has a digital display that shows plant power factor, plant current level and plant voltage level. Set point power factor is set by digital display.

REACTORS

Reactors are designedspecifically for each application and include:

- Standard iron core design.

- Air core reactors based on application requirements.

-3 Phase reactors up to 4.16kV.

-Single phase reactors at higher voltages.

- Reactors for de-tuned and harmonic filter banks are supplied with insulation levels in acordance with harmonic loads.
