Harmonics Mitigation Solution

Value proposition

Main drivers

• Eliminate Voltage distortion:

     - Excessive temperature rise in motors

     - Electrical noises

     - Sensitive electronic equipment malfunction

• Eliminate increase in the apparent power and over-sizing of sources (UPS, Genset, etc.), capacitors, cables...

     - Derating of electrical equipment or over-sizing

     - Accelerated ageing of equipment

• Eliminate Flow of current in the neutral conductor and consequently in the PEN:

     - Excessive temperature rise in transformer

     - Tripping of circuit breakers

Value proposition
