A must-see for testing coil components such as inverter motor coils and industrial products!
The "DWX-05PD" is a testing machine that enables partial discharge testing within coils. It can perform partial discharge tests required for the insulation reliability testing of coils, as well as insulation tests for motors, transformers, and other coils used in home appliances, automotive products, and industrial products, allowing for simultaneous AC withstand voltage testing and partial discharge testing. This groundbreaking testing device allows for high-sensitivity pass/fail judgments with simple operations, even without specialized knowledge, and is expected to shorten testing time and reduce the cost of testing equipment. 【Features】 ■ Two necessary tests for coil testing in one device ■ Achieves advanced coil testing at a low cost ■ Stable testing unaffected by environmental conditions ■ Packed with diverse and convenient testing functions *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Other Features】 - Direct detection of partial discharge occurring inside the test coil using electromagnetic waves. - Detection of high-frequency signals where partial discharge occurs, using a narrowband antenna. - High-sensitivity partial discharge testing is possible by placing the antenna close to the test coil. - Easy handling with minimal influence from the test circuit, facilitating integration into production lines. - Automation of partial discharge testing is possible. - The already introduced impulse winding tester (DWX series) can be retrofitted with a partial discharge detection sensor (microwave sensor module) as an option. - Convenient functions necessary for evaluating partial discharge testing improve work efficiency. - Discharge signals can be displayed as waveforms, making them visually understandable and easy to use. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Since our founding, we have focused on the development and manufacturing of various measuring instruments as a research and development-oriented company. Among these, the "Impulse Winding Tester" is used to inspect the damage of winding components in various motors and transformers used in LCD TVs, automobiles, and more. We have a strong track record of deliveries not only in Japan but also in China, South Korea, Taiwan, and other countries, receiving high praise. It allows for easy non-destructive testing of all good/bad judgments of winding components, including differences in winding count, material, and insulation defects. We develop and manufacture this testing machine domestically. Additionally, looking towards the next generation, we are conducting research themed on environmental purification, leveraging high-voltage impulse power supply technology in collaboration with universities.
