Such non-linear electrical equipment as high power rectifier installed in enterprise’s power distribution system and power grid for operation

will inject harmonic current to the power distribution system and power grid. It will also generate the large number of various harmonic components and affect directly the power supply quality of the grid. At the same time

as a large electrolysis enterprise

once the power factor of rectifier power is less than 0.9

the output power of equipment is reduced

the equipment’s insulation is heated and aged and therefore the efficiency is reduced and

moreover

the burden is added to the power grid. The power transmission ability of the power grid is reduced. Therefore

the filter compensation device must be installed in the electrolytic rectifier power supply system.
