AC - High Voltage Insulation Testers

AC - High Voltage Insulation Testers

High voltage insulation testers indicate breakdowns, grounds, and shorts.  Use them to apply a high-voltage test at various steps in the manufacture or repair of electrical products.  This permits early detection of insulation weakness or failure that might otherwise show up only in the actual use.
These testers are built with a breakdown light which also serves as an "on" light.  This indicating light dims or goes out completely to indicate a problem.
In addition, 4 models have a built-in safety switch that immediately stops current flow in the event of a breakdown.  Along with the visual indication of a problem these units also have a buzzer which signals a problem.  These units will shut down in the event of a breakdown and will not start up again until the start/reset button is reset.
All units are supplied with self retracting probed test leads.  The probes are spring loaded and housed within the insulated fibre handles.  The fibre slide buttons are pressed to expose the test probes.  This safety feature minimizes the chance of accidental contact with the probes.

5000V DC Hipot
This Model meets the UL, CSA, VDE, IEC, and UL
     120K Ohm test requirement.  This unit feature
     audible and visual failure alarms, and shut off high
     voltage upon reject.
Operators can set output voltages and trip
     currents to desired levels in the absence of any
     high voltage, a key safety feature that
     conventional analog hipot testers lack.
Easy-to read digital display simplifies the task of
     setting test parameters and interpreting test
     results.  Meter memory allows operators to review
     the last test results.
