There are many power converter using a harmonic current flows, and hence a lot of distortion waveform generating temperature increase of the apparatus and Is the cause of a malfunction, the information communication device jangaedeung due to noise. Is used in the equipment of the high-pressure filter to prevent this RLC filter unit.
- Consisting of a high-pressure non-inductive resistor theft -

1. For removing the train and Acropolis rising wave
2. INVER5TER for circuit RESTE
3. voltage fluctuation compensation device
4. Improve power factor compensation device
