High harmonics, variable loads

The PowerVar Filter are large automatic industrial grade capacitor banks intended for deployment on variable loads in environments with high harmonic distortion. It comes standard with high temperature and harmonic rated capacitor cells. It ranges from 75 to 1200 kvar and offers from 3 to 12 steps with fuse protection. 

The standard design is tuned to 3.78th in order to have a resonance free power factor compensation for harmonic distorted network. The reactor core is designed with multiple air gaps to reduce the heat generated by the harmonic currents, thus increasing the performance and service life. Additional tuning frequencies are available for specific applications. 

The PowerVar Filter is designed to ensure maximum safety and extended product life. The capacitor banks are built with self-healing cells with segmented metallized film that withstand high levels of harmonics. The metallized polypropylene coil immediately seals any punctured areas caused by electrical arcs. The cells are also equipped with a 3-phase overpressure disconnect to prevent them from bursting in case of excessive pressure. These capacitors have screwless terminations that secure wiring with a maintenance free, antivibration connection.


The design is suitable for any type of industrial network with high harmonic distortion level.

It is recommended to improve the power factor on site or feeder level of medium to large industries with variable loads.
