A 10kV cable, running outdoors, failed due to a fault. After removing the fault point, the cable sections before and after the fault need to be insulation-tested to ensure no other defects. After making a new joint to restore the cable connection, a high-voltage pressure test is performed to verify the integrity of the joint and the cable's insulation.
Complex environment, making it inconvenient to use conventional equipment.
Complex operation and lengthy testing process, requiring multiple devices and manual steps.
The solution involves using an Insulation Resistance Tester to assess the insulation of the cable and a Frequency Converter Series Resonance Device for the high-voltage pressure test. The series resonance device is portable and combines a lightweight reactor for flexible setup, allowing efficient testing in challenging outdoor conditions.
Easy to transport and set up in outdoor locations, minimizing equipment hassles.
Fully automated process for both insulation testing and pressure testing, reducing operational complexity and improving efficiency.
Quick test results, ensuring safe operation of the cable joint without additional downtime.
