Prevent insulation failure in electrical appliances before it occurs! Rental of partial discharge and corona discharge testing equipment.
Partial discharge and corona discharge, which occur frequently in high-frequency and high-voltage components, degrade insulation performance and can lead to defects. However, due to the low voltage, they cannot be detected in standard product inspections. To identify the causes of insulation failure, we offer rental of the "Partial Discharge and Corona Discharge Testing Machine XT Series." For more details, please contact us.
Inquire About This Product
basic information
Partial discharge and corona discharge are phenomena where gas is ionized in areas with high electric fields, leading to the occurrence of sparks. Although not well-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 saving, can also be breeding grounds for partial discharge and corona discharge. For those troubled by unexplained failures, we are currently renting out the "Partial Discharge and Corona Discharge Testing Machine XT Series." 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.
