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 ...

Why is VLF Hipot testing becoming more important in modern power networks? VLF Hipot testing is widely used for assessing the ...

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 ...

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 ...

Hipot data? That is an oxymoron. A hipot test, also known as dielectric breakdown, is a simple test: Apply high voltage to the insulation barrier of the DUT and ensure there is no breakdown. It is a ...

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.

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 ...

The deployment of renewables has been growing at a rapid pace in recent years, reaching record levels, according to IRENA. Among all renewable technologies, solar photovoltaic (PV) power has been ...
