Sikes passive harmonic filter testing video. Rated power:110kw  THDi≤7.5% @ 60% load.

Sikes passive harmonic filter is designed for almost any kind of electronic applications with six pulse front end rectifiers . The filter can efficiently reduce the harmonic current distortion to required level.
Typical application:non-linear three-phase power supplies where potential risk is high due to thermal and electrical overload caused by harmonic currents.
