Active Harmonic Filter AHF

Jinneng electric active harmonic filter AHF is defined as an electronic device that enhances the quality of electrical energy by removing current and voltage harmonics, compensating for reactive power, and addressing various unbalanced and flicker effects in electrical systems. It consists of a power circuit, control system, and sensors to monitor its operational parameters.

 

The active harmonic filter intend to provide compensation for voltage harmonics, voltage unbalance to the utilities as well as current harmonics and current imbalance to the consumers.

These active power filters provide mitigation of harmonic disturbances of voltage and current, voltage notch, sudden voltage distortion, transient disturbances and power factor improvement effectively in medium power applications

 

 

AHF series products can be divided into rack type, wall type and vertical type according to the installation mode. Each type of installation mode module has products with voltage levels of 200V/400V/480V and 690V/800V, and the product capacity covers 50A~200A.
