The ZGR FAA / AHF helps to eliminate harmonic contamination in the grid, reducing power quality problems and enhancing a more efficient and safe use
The presence of harmonics increases the RMS current in electricity grids. The transmission of currents harmonics through system impedance creates harmonics which produce voltage distortions and in this way deteriorate the quality of the grid voltage. This leads to increased operation and energy costs, production/process stops, overheating and malfunctioning of electrical equipment.
The ZGR FAA / AHF is designed according to the latest state of the art in power electronics technology.
The technology is installed in parallel with non-linear electrical loads. The active filter analyses the phase current together with the associated harmonics,
generating a compensation current, which neutralizes the harmonic currents creating a practically sinusoidal waveform.
