High Voltage Insulation Testers

About HV Insulation Testers

Measurements of insulation on high voltage cables are extremely important and ensure that the insulation hasn't degraded to such a point that the cable becomes a hazard to those around it.

High voltage insulation testers check the insulation of a system by using several test voltages to determine the overall resistance range of the cable. If degradation has taken place, the resistance level will be below an acceptable threshold and action should be taken to repair the system.
