13. ABSTRACT (Maximum 200 words)
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. Itis 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 waming 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.
