As DC high-potential testing starts to show its age, test methods recommended by IEEE are ready to fill the void For many years, high-voltage DC testing has been the traditionally accepted method to ...

Users and manufacturers of wiring and cabling typically measure the Insulation Resistance of the cable on reels (spools). These reels may hold literally miles of cable. Figure 1 illustrates one such ...

The High Voltage, Inc. VLF series of AC Hipots enables utilities to economically AC field-test cables and electrical apparatus instead of DC testing. A VLF unit is an AC hipot with a 0.1 Hz or lower ...

Associated Research has added two models to its HypotUltra line that offer AC hipot, DC hipot, insulation resistance, and ground bond testing. The Model 7804 is a 5-kV AC hipot and 6-kV DC hipot ...

Cable/harness testers traditionally have checked for shorts and opens in completed wiring assemblies. Hipot capabilities were added to support insulation resistance and dielectric withstand testing up ...

Haefely Hipotronics has launched a new DC Hipot “How-To” Video. The “How-To” series takes viewers behind-the-scenes with a Haefely Hipotronics industry expert to demonstrate a live test. This video ...

I once designed a product for Avaya, a 1U x 19" rack with an open-framed OEM power supply. Yields were good at first. Later, HIPOT (high-potential) testing started to fail on random units at a 10 ...
