- Harmonic filtering function: can filter 2-51 times harmonic in the same time, efficiency up to 97%;
- Reactive compensation function:1) constant reactive power mode;2) constant power factor mode;
- Unbalance compensation:Balance the three-phase current of the system to avoid single-phase overload of the transformer and improve the effective use capacity;
- Other basic functions:The 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.
Before APF is running, THDI is 26%: After APF is power on, THDI was dropped to 6%:
