Abstract

AN ARCING FAULT PROTECTION SYSTEM FOR A SWITCHGEAR ENCLOSURE (10) INCLUDES A SWITCHING DEVICE FOR RAPIDLY DIVERTING CURRENT FROM THE SOURCE BUS (22) OF AN ELECTRICAL DISTRIBUTION SYSTEM IN RESPONSE TO THE DETECTION OF ARCING FAULTS IN THE SYSTEM. THE SWITCHING DEVICE, WHICH MAY COMPRISE A MECHANICAL SWITCH (52), A SOLID-STATE SWITCH (90; 92) OR HYBRID DEVICE (130, 140), QUICKLY DIVERTS CURRENT CARRIED ON THE SOURCE BUS (22) TO EFFECTIVELY EXTINGUISH ARCING FAULT CURRENTS PRESENT IN THE DISTRIBUTION SYSTEM, PREVENTING THE GENERATION OF GASES AT HIGH PRESSURES AND / OR TEMPERATURES SO AS TO PROTECT THE SWITCHGEAR EQUIPMENT FROM DAMAGE.
