LV Power Factor Correction Systems

Choosing the size of the power factor correction equipment is preceded by an accurate preliminary assessment of the plant’s design data and, where possible, an analysis of the electricity bills. The type of power factor correction must be chosen depending on the harmonic distortion rate of the plant’s current (THDIR%) and the ratio between reactive power (in kvar) of the power factor correction equipment to be installed and the apparent power (in kVA) of the MV/LV transformer. The 4 reasons to have power factor corrections: Economic convenience, Energy efficiency, Power quality and Electricity Authorities.
