Product Description

ZXWXZ Series Series Resonance Test Device Without Partial Discharge

   

ZXWXZ discharge series resonance test device series is mainly used for all kinds of insulation materials, insulation structure and the insulation of the power frequency voltage electrical products, such as tolerance levels, also as transformer, transformer, lightning arrester and try no electrician frequency partial discharge test power, widely used in electrical manufacturing, electric power operation departments, scientific research units and institutions of higher learning. The 50-2250kV series resonance test device without local discharge has passed the ministry-level product appraisal. No local discharge resonance can accurately detect the internal insulation performance of the main transformer, transformer, GIS, cable, bushings, arc suppression coil, current capacitor and other special tested products that require local discharge test, reflect the local discharge situation of the internal insulation, predict the service life of the tested products, and eliminate safety risks from the source.
