Product Description
Characteristic of Our AHF/APF:
- Unbalance compensation
- for harmonics or reactive power first;
- The protection level of the system reaches IP20;
- Can withstand 2.5 times overload of 10ms.
- 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.
- By setting, you can choose whether to compensate
- Other basic functions
- Balance the three-phase current of the system to avoid single-phase overload of the transformer and improve the effective use capacity;
- Harmonic filtering function
- Up 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 function
- With 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;
