Abstract

The nature of loads in the Low Voltage (LV) systems is predominantly inductive. This leads to a lagging power factor in LV networks and hence it is essential to compensate for the lagging power factor with suitable LV capacitor banks. Low Voltage power factor compensation is done with shunt capacitors to maintain a power factor closer to unity. For LV shunt power factor compensation, LV capacitors of the Metallized Polypropylene (MPP) type are predominantly used. When used in LV systems, these capacitors are operated under full load and generally operate at maximum operating temperature. A study was undertaken to identify the reactive power output under such conditions in MPP-type capacitors of similar voltage and different power ratings and the results of the study are discussed in this paper.
