ABSTRACT:
A process for detecting arc discharges in power cables connecting power supply board and at least one equipment rack, the power supply board including circuit breakers operable at a preset current level, said arc discharge occurring at a fraction of said current level. After the arc discharge is detected, a signal representing the presence of the arc discharge is supplied to a power supply control, and a control signal is provided by the power supply control to cause said at least one circuit breaker to open interrupting supply of power to an affected power cable.
