Low-voltage Switchgear Arc Flash Solutions General Other protection options n Infrared Viewing ports n Zone Selective Interlocking n High Resistance Grounding 14 SWITCHGEAR Infrared Viewing Ports Infrared viewing ports allow maintenance personnel to monitor temperatures of the cable and bus connection points in the rear of the gear while it is energized and under load. Excessive temperatures can be an indication of a problem with a connection. Zone Selective Interlocking Zone Selective Interlocking eliminates any intentional time delay in the event a fault occurs between two breakers in adjacent zones. In the schematic to the right, representative time delay values are shown for the breakers in each zone. If a fault occurs on the load side of the downstream breaker, the ZSI system enables the upstream breaker’s delay and allows the downstream device more time to independently clear the fault. If the fault occurs on the line side of the downstream breaker (between two zones), the delay in the upstream breaker will not occur. This allows the fastest tripping time for faults and will reduce the amount of arc energy which may be released. The ZSI function is available for short time delays and ground fault delays. Infrared viewing ports High Resistance Grounding Research has shown that a high percentage of arc faults start as a phase to ground fault. High resistance grounding systems minimize the available phase to ground arcing current. Zone Selective Interlocking A high resistance grounding system reduces the magnitude of phase to ground faults. This will reduce the mechanical stress on equipment for the most common of faults and will reduce the magnitude of energy released.
