ATEC carries partial discharge testers and corona cameras, as well as more partial discharge test equipment from leading manufacturers like OMICRON, Hipotronics, and Doble. ATEC’s inventory can be paired with other equipment for a variety of electrical tests.
A partial discharge is a small spark within electrical insulation caused by insulation breakdown, and occurs when the insulation system experiences high voltage stress. A dielectric breakdown of a small portion generates electrical discharges, which bridge the gap between two conducting electrodes. These breakdowns manifest across the surface of insulation material, in pockets found in solid insulation, within gas bubbles in liquid forms of insulation, and proximal to electrodes in gases.
Partial discharge eventually destroys insulation, which leads to electrical breakdowns, and at times even degradation or total failure of the equipment. Preemptive testing measures the PDs occuring and pinpoints their location to streamline diagnosis and repair processes, so it is essential for substation and transmission line maintenance.
ATEC has a variety of partial discharge test equipment available for rent. Reach out to one of our rental experts to discuss options or request a quote.
