The most effective way to eliminate harmonics is active harmonic filter.
There is an increasing number of electrical equipment with non-linear voltage-current characteristics connected to the network. Harmonic currents produced by them cause harmonic voltages in network impedances, which add to the fundamental system voltage resulting in voltage distortion.
This voltage distortion is experienced by all electrical equipment connected to the network, leading to higher thermal loading of motors, transformers, capacitors, switch-gear and cabling. Some of the electrical equipment develops a more audible noise when supplied with distorted voltage. Sensitive electronic protection, control and ripple control systems are not likely to operate properly when supplied with distorted voltage.
A variety of solutions exist to eliminate the problems of harmonics. Active filter’s patented Direct Phase Current Control (DPCC) technology together with advanced digital processing provides your network with efficient and fast harmonic reduction and reactive power compensation.
