China AC380V400V50Hz ACTIVE HARMONIC FILTER

Product Description

The WBAPF three-level series active filter can directly or indirectly measure the current injected into the grid by a non­linear load through a connected external current transformer. The detection and operation of harmonic and reactive compensation are performed in the digital control unit. The active filter generates a compensation current that cancels the harmonic components and the load reactive current, so that there is only a fundamental current in the grid. The active filter is able to adapt the changes in the magnitude of the load and system harmonic content in real time so that it can be treated at any time

Product Features

Harmonic filtering functionUp to 51 harmonics can be filtered out;Within the capacity range, the effective filtering ability of the target harmonics reaches 97%;Select and filter all the harmonics within 51 times at the same time, and set the filtering ratio of each harmonic;;With fast harmonic compensation, response time ≤5ms;Reactive compensation functionWith reactive power compensation capability, that is power factor adjustment capability;Provide two reactive power compensation modes : 1) constant reactive power mode; 2)constant power factor mode;Unbalance compensationBalance the three-phase current of the system to avoid single-phase overload of the transformer and improve the effective use capacity;Other basic functionsThe CT can be installed on the load side or the grid side according to the user's choice. The device can be automatically compatible with the CT phase sequence.By setting, you can choose whether to compensatefor harmonics or reactive power first;The protection level of the system reaches IP20;Can withstand 2.5 times overload of 10ms.

An Actual Case of the AHF/APF:

Before the APF/AHF switch on: There are harmonic and reactive losses in the grid, resulting in power quality problemsAfter the APF/AHF switch on: generating reverse harmonic current and reactive current, dynamically compensating for harmonics and reactive power, guaranteed power quality
