Power Factor Correction Capacitors Sizing Calculations – Part …

At capacitor switching while one or more capacitors are connected to the system, the switching capacitor will see a high inrush current. This is due to the current flow from the already connected capacitor(s) (which will act as a source) through the least impedance path set by the switched capacitor along with the current from the main source.
