The manufacturing of these units can be done similarly to 1- phase unit. This material allows each plate to hold an equal and opposite charge. This compares the Southern States CapSwitcher with a circuit switcher used in capacitor bank error: Content is protected !! Inputs: electrical charge (Q) electrical potential (V) Because the bulk of loads is inductive, they require a certain amount of reactive power to operate. Substituting 1 and 2 into our expression for Qc we get: where PF 1 and PF 2 are initial and improved PF respectively (if you have PF expressed in percentage, you need to divide it by 100). They also impact the failuremodality of the capacitor element and impact the setting of the capacitor bank protection.
