The MOEORW-WHVA series integrated VLF dielectric loss high voltage generator is a high-precision insulation testing device designed specifically for 10kV, 20kV, and 35kV medium-voltage power cables. It integrates functions such as 0.1Hz VLF withstand voltage test, dielectric loss tanδ measurement, DC withstand voltage, insulation resistance test, and sheath fault location. It strictly follows national standards and power industry standards and is suitable for cable handover testing, preventive testing, fault diagnosis, and daily inspection. It features simple operation, safety and reliability, accurate testing, and convenient mobility, meeting the needs of efficient on-site operations.

Core advantages
1. One device, multiple uses, saving money and time.
One unit can complete withstand voltage, dielectric loss, DC, and sheath testing without the need for multiple devices to be rotated. This reduces on-site wiring, handling, and setup, significantly improving efficiency.
2. The voltage level was precisely matched to the cable, and the cable passed the acceptance test on the first attempt.
10kV cables use 34kV, 35kV cables use 45kV, high voltage accuracy reaches 0.001kV, no overvoltage or undervoltage, compliant testing and reliable data.
3. Fully automatic dielectric loss detection, results in 3 minutes and 30 seconds.
It automatically performs three-point tests at 0.5U0/1.0U0/1.5U0, automatically calculates stability and difference, and directly judges normal/caution/abnormal without manual calculation.
4. Export data with one click and automatically generate standard reports.
Test data is automatically saved, exported to a USB drive, and the accompanying software directly generates a formal test report, eliminating the need for manual spreadsheet organization.
5. Safety protection measures are in place to eliminate the risk of misoperation.
Automatic high voltage disconnection in case of overvoltage/overcurrent/breakdown, automatic discharge upon completion of test, equipped with an emergency stop button and a two-person operation mechanism for enhanced safety.
6. Reasonable structure, easy to use on site
The W HVA30/34/45 /81 is an integrated portable case that can be carried by a single person and is ready to use right out of the box.
The W HVA80 is a split-type unit with stronger load capacity, making it suitable for scenarios with long cables and large capacitors, and providing more stable output.
