Electrical EQUIPMENT
General Information
Active Harmonic Filter operates on the base of a three-level topology circuit,
providing power quality solutions such as harmonic elimination, stepless power factor correction,
and load balancing. The AHF module capacity of AHF modular ranges from
30A to 150A and allows up to
20 modules to connect in parallel, enabling users to easily achieve the target
filter current capacity.
Product Value
- Eliminate the harmonic current of nonlinear loads.
- Improve the operating efficiency of the power system and reduce the downtime of the power
distribution system, especially for low-voltage systems with frequent load upgrades. - Meet the strict requirements of utilities for electrical energy quality, avoid fines and
power supply interruptions caused by electrical quality problems, and reduce carbon dioxide
emissions.
