Why Your Capacitor Bank Should be Left Ungrounded
Figure 1 is used to illustrate how a grounded capacitor bank can interfere with the ground fault protection system of a resistive grounded system. The main concern arises when a capacitor fails as shown in Figure 1 by the "X". Since medium voltage capacitors fail shorted, a faulted capacitor is like applying a line to ground fault on the facilities
