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 ...

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 ...

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 ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Certifying a new power product to relevant safety standards is an essential part of any design and development process.

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 ...
