    The Model 2620 may also be used simply as a highly accurate clamp-on current probe. With its 4 in jaw opening and range of 500 µA to 400 A, the Model 2620 provides a versatile way to analyze unbalanced current measurements, leakage values on grounding conductors and ground loop currents.

    This installation has no faults. If you clamp the detector around the cables at points A,B,C or D, it will output zero. 115V/230V OVEN MOTOR ZERO ZERO AMPERE AMPERE Figure 1 Leakage Current Probe Model 2620 - User Manual...

  • Page 13: Equipment Troubleshooting

    In Figure 2, there is a fault in the installation. At point A, the Model 2620 detects 1 A (the difference between 16 A and 15 A), indicating a fault downstream. At point C, it detects zero; therefore, the fault is not in the oven. At points B and D, the detector picks up 1 A, showing that the fault is in the motor.

    If possible, take your measurement where you can avoid closing the shield in the clamp, such as the nearest control panel or inside the connecting box of the motor. Figure 3 Figure 4 Leakage Current Probe Model 2620 - User Manual...
  • Page 15 One way to circumvent this shielded cable problem is shown in Figures 5 and 6. Here the shield is looped through the detector twice, so that the reading will be that of the fault current. Figure 5 Figure 6 Leakage Current Probe Model 2620 - User Manual...

  • Page 16: Grounded Neutral

    400 mA fault and a 250 mA fault on the same phase, the Model 2620 will detect 650 mA. But if the two faults are on different phases, they add vectorially and may even sum up to zero.

  • Page 17: Neutral Grounded Through An Impedance

    A. The Model 2620 will detect electrical faults while the equipment is still in operation. This offers two distinct advantages. First, it is not necessary to shut the equipment down, eliminating costly down time;...
  • Page 18 Q. Would it be possible to clamp the Model 2620 directly around the grounding detector? A. Yes, in some instances it may be possible to detect fault current on a specific motor if there is a dedicated grounding path. However, if several devices are sharing a common ground, it should be noted that the fault may be occurring on any one (or multiple) of the devices.

    ■ Do not use any abrasives or solvents. ■ If rusted, the jaw mating surfaces of the Model 2620 may be lightly sanded with very fine sandpaper and then very lightly oiled. Wipe off excess oil and do not let it drip into the case.Repair and Calibration 5.2 REPAIR AND CALIBRATION...
