Measures leakage current directly and locates faults while preventing down time
Excellent for checking leakage in splices without load interruption
Operates on a single cable or bundle
Clamps easily onto any size conductor (select Jaw opening: 2.5″, 3.5″, 4.5″, 6″ and 9")
Maximum operating temperature range -5°F to 150°F (-20°C to +65°C)
Attach to hot stick with a clamp on adapter installed by STB (additional option)
The detector is a clamp-on current transformer that is sensitive to AC currents passing through it. When a generator supplies an AC load through a pair of wires in an insulated cable, the current going out on one wire is equal to the current coming back on its return. The sum equals zero. A ground fault changes this equality, and the current leakage detector detects it, measures it, and indicates the severity of the fault causing the imbalance.
Circuit breakers and fixed current monitors are designed to open the circuit or warn of ground faults as they occur. They react to failures in the circuit, but do not indicate their causes. The current leakage detector is designed to isolate these impending failures before they become serious enough to cause a fire or a serious shutdown.
