Panel AHF Active Harmonic Filter Hefftron Wall Mounted
AHF is applied to realize dynamic tracking compensation and on demand allocation of active filtering, reactive power compensation and unbalanced current compensation.
In an electric power system, a harmonic of a voltage or current waveform is a sinusoidal wave whose frequency is an integer multiple of the fundamental frequency. Harmonic frequencies are produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated electric machines. They are a frequent cause of power quality problems and can result in increased equipment and conductor heating, misfiring in variable speed drives, and torque pulsations in motors and generators.
The impact of harmonic pollution is an increasing problem given the growth of sophisticated power electronics and the proliferation of non linear loads in power systems. Such loads are increasingly used in all industrial, commercial and residential installations.
