Ideal for preventing insulation failures due to partial discharge and corona discharge, and for trouble prevention in high-frequency, high-voltage components.
Partial discharge and corona discharge, which often occur in high-frequency and high-voltage components, can degrade insulation performance and cause defects. However, due to the low voltage, they are not typically detected in standard product inspections. To uncover the invisible causes of insulation failures, we recommend our contracted inspection services. Please contact us for more details.
Inquire About This Product
basic information
Partial discharge and corona discharge are phenomena where gas ionizes in areas of high electric fields, resulting in the occurrence of sparks. Although still not widely known, they degrade insulation performance and affect lifespan. High-voltage printed circuit boards, connectors, and connecting cables require caution. Inverter control devices, which are increasingly being adopted for energy savings, can also be breeding grounds for partial discharge and corona discharge. For those troubled by unexplained insulation failures, affordable contract testing is recommended. Please contact us for more details.

Company information
Our Adfox XT series can be tested at frequencies and voltages close to the actual operating circuits of the products. The latest XT-330 can apply a continuous sine wave of 10kVrms at 100kHz, and it can be used for non-destructive testing that instantly stops when corona discharge (partial discharge) is detected, as well as durability testing that takes advantage of high output. Additionally, measurement results can be aggregated on a PC. Adfox Co., Ltd. is a Japanese manufacturer located in Ome City, Tokyo, and our products range from corona testers, sound collectors (hearing aids), to binaural microphones. We also offer OEM products, so please feel free to consult with us.
