The effects of system harmonics power pollution is an increasing problem given the growth of sophisticated electronics and proliferation of non-linear loads in commercial and industrial applications.
Non-linear loads are a result of systems that use frequency converter, drives, welding machines and applications that consume non-sinusoidal-shaped or unsymmetrical currents from the network. These generate a significant level of harmonics currents. The acute problem with harmonic currents is that they lead to issues such as thermal losses in cables, distribution panels, transformers, overloading and unstable network conditions due to unsymmetrical currents.
Active Harmonic Filters provide reduction of system harmonics as well as highly dynamic reactive power compensation. Connected in parallel with the harmonic-generating loads, the Active Filter analyses the system harmonics profile and “injects” a counter-phase harmonic compensation current into the network, i.e. neutralising the corresponding harmonic distortions in the system.
