basic information
【Features】 ■ By applying a sine wave of any frequency (30k to 80kHz) with the required voltage (0 to 40Vrms) and current (0 to 5Arms) to the primary side of a high-voltage generation transformer, high voltage (0 to 5kVrms) is generated on the secondary side. This allows for the high-speed measurement of partial discharge, corona discharge, and spark discharge, enabling pass/fail judgment against the set conditions. ■ Accurate detection of partial discharge and corona discharge, which have been difficult to detect until now. ■ Contributes to improving product reliability. ■ If there are issues such as winding entanglement, section skipping (wound with other sections), or inclusion of scrap wire (pieces of cut wire), partial discharge and corona discharge can occur even at the specified voltage, leading to a judgment of failure. □ For other functions and details, please contact us.

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.
