APF is also parallel connected to the system. It can trace the load current wave forms and output the harmonic current for compensation by calculation. It introduces compensation current with a reverse phase to the power supply system by the control of IGBT. It can also provide current of leading or lagging phase to improve the power factor of the grid. APF can be equivalent to filter that gives a very low impedance path to the harmonics injected to the system. In this way the harmonics can be eliminated by short circuit to the harmonics. Environment Installation type：Indoor Operation Temperature: -25℃～+55℃ Saving Temperature: -40℃～65 Humidity: Max 95% Altitude:≤2000 Benefits of harmonic control 1. Secure the reliable operation of power supply and distribution system. After harmonic control, it can not only save the user’s energy consumption but also reduce the line loss of the grid. The reduction of the harmonic pollution may improve the quality of power system. 2. Improve the reliability of electrical equipments and extend the equipment life. The harmonic control and reactive power compensation may avoid the over voltage and current of the devices caused by harmonics. The life of single phase devices may increases by 32%. The life of three phase device may increases by 20%. It is about 5% increased with the transformer.
