Remote testing of high-voltage insulators

An integrated two-channel method has been suggested for remote testing of operating condition of high-voltage insulators. The method is based on concurrent registration and computer processing of partial-discharge signals that are detected by electromagnetic and acoustic sensors. Using the device th...

Description
Summary:An integrated two-channel method has been suggested for remote testing of operating condition of high-voltage insulators. The method is based on concurrent registration and computer processing of partial-discharge signals that are detected by electromagnetic and acoustic sensors. Using the device that was created based on this method, diagnostic signs have been established that make it possible to distinguish between functional and faulty insulators under real service conditions.
