A Test Circuit for Capacitor Bank Grounding Sticks
Abstract
After completion of a charge-discharge cycle, energy-storage capacitor banks must be shorted to ground and the short maintained before the bank can be safely approached by an operator. It is essential that the grounding stick used by the operator to drain any residual charge have a proper electrical resistance. A test unit has been constructed and tested which checks the grounding circuit for proper resistance and provides a visual indication of its status. This unit also includes an auxiliary circuit which sounds an audible warning when an excessive current passes through the grounding circuit. The enhanced measure of safety which such a circuit could provide is illustrated by discussion of a recent capacitor-bank accident at Aberdeen Proving Ground, MD.
