HV Cable Grounding Condition Live-Line Tester

HV Cable Grounding Condition Live-Line Tester

The MOEORW-WRT910 cable grounding status live diagnostic instrument is a professional device for testing high-voltage cable grounding circuits. It can accurately measure resistance under live conditions, has strong anti-interference capabilities, and is easy to operate. It is suitable for scenarios such as daily inspection, fault diagnosis, and maintenance and acceptance of high-voltage cables.

The live-line diagnostic instrument for cable grounding status is mainly used for testing the resistance of high-voltage cable grounding loops. This instrument employs a high-performance microcontroller for control and a high-precision AD chip for sampling, enabling accurate and rapid measurement of cable grounding loop resistance even when the line is energized. It is powered internally by a rechargeable lithium battery; it can automatically or manually switch test loops and automatically calculate the resistance of each phase; it can be wirelessly operated via an app and the measurement results can be transmitted. This device is suitable for the rapid detection of cable grounding loop status.
