Product Introduction

Ultrasonic discharge detector is applied to partial discharge live circuit detection of transformer, reactor, generator, transformer, bushing, GIS, power cable, power capacitor, CVT, arrester, high voltage switch, switch cabinet and other ac/dc high voltage electrical equipment with various voltage levels and capacities.

When partial discharge occurs, physical phenomena such as ultrasonic wave, heat wave, light wave and magnetic wave will be generated. The ultrasonic wave will spread around in the form of spherical wave with the sound source as the center. Htjf-9002 Ultrasonic discharge detector USES the Ultrasonic signal generated by local discharge to judge the existence and location of local discharge. Combined with the real-time images and data, it can quickly diagnose the status of local discharge. The tester integrates transient voltage to ground and ultrasonic.

Product Names:partial discharge detector、ultrasonic partial discharge detector
