Product Details
■Product Overview
The partial-discharge‑free series resonant test system is primarily used to evaluate the dielectric withstand voltage levels of various insulating materials, insulation structures, and electrical equipment under power-frequency conditions. , It also serves as a partial-discharge‑free power supply for AC frequency tests of test specimens such as transformers, instrument transformers, and surge arresters. , It is widely used in electrical manufacturing departments, power operation departments, research institutions, and higher education institutions. 50-2250kV The partial-discharge‑free series resonant test system has passed ministerial‑level product appraisal. Its key technical performance indicators are at the forefront domestically and have reached the advanced level of comparable international products. The partial‑discharge‑free resonant system can accurately detect main transformers, instrument transformers, GIS The internal insulation performance of certain special test specimens—such as cables, bushings, arc-suppression coils, and current capacitors—that are required to undergo partial discharge testing. , Microscopic reflection of internal insulation partial discharge conditions , Predict the service life of the test specimen and eliminate safety hazards at the source.
