D-KHR Series - 10Kv, 12Kv & 15Kv - Digital Surge Tester

About the D-10KHR, D-12KHR & D-15KHR

The Digital Surge Tester is designed for testing the coils and windings of medium-range AC rotating machines up to 6.6kV.
It integrates Surge Testing, DC Hi-Pot Testing, and Resistance Testing in one system, providing a highly reliable solution for manufacturers and repair workshops.
With an embedded industrial PC, 8-inch touchscreen display, and software for storing, recalling, and printing test reports, this tester ensures efficient operation in production and maintenance environments.
