The Model 2620 measures leakage current shunted
to ground caused by insulation faults. It enables the operator
to locate failures when they occur, or anticipate them before
they occur, without shutting down equipment or spending hours
troubleshooting.
It is designed specifically for locating low
current faults on high current loads. The detector is a sensitive
nickel alloy AC current transformer capable of measuring differential
or leakage current as low as 500ľA, and may be used to measure
current up to 400A continuous duty.
The Model 2620 provides two output ranges:
1mV/mAac or 1mV/Aac. The output leads are terminated with
standard 4mm banana plugs capable of interfacing with any
standard multimeter. With its 4" jaw opening and range of
500ľA to 200A, the Model 2620 provides a versatile way to
analyze unbalanced current measurements, leakage values on
grounding conductors and ground loop currents.
