Active harmonic filters have been developed in response to the increasing needs in modern electrical systems related to power quality issues of electrical supply networks. They function by actively detecting and measuring the harmonic currents in the electrical network and generating offsetting currents to those harmonics and thus eliminate the created distortions. This technology not only boosts the power factor, but also improves the efficiency and reliability of your electrical system.
