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 ...

DC testing of solid dielectric cable is largely ineffective, highly discouraged, and discontinued by most. The preferred method is to use AC voltage to test cables, and for long cable runs, a Very Low ...

To meet the requirements of your electrical safety testing applications, you can choose from a variety of instruments and systems that perform hipot, insulation-resistance (IR), ground-resistance, and ...
