Dielectric Loss Tester

Main Functions and Features

1. The instrument features a full-touch, large LCD display for easy operation, high accuracy, and strong anti-interference capabilities.

2. Test results are saved and historical records can be viewed at any time. A built-in thermal printer is included for printouts.

3. It features a reverse-wiring low-voltage shielding function. Even with a grounded 220kV CVT busbar, it can perform 10kV reverse-wiring dielectric loss measurement on C11 without removing the wires.

4. It can perform AC withstand voltage tests, facilitating AC withstand voltage testing on PT and CT secondary circuits, as well as withstand voltage tests on 400V low-voltage systems.

5. It can detect external high-voltage power supply frequencies of 40Hz to 70Hz, allowing high-capacity, high-voltage dielectric loss tests to be performed using power-frequency power supplies or series resonant power supplies.

6. It has a computer interface. One computer can control up to 32 instruments and can be integrated into a comprehensive high-voltage test vehicle for measurement, data processing, and report output.

7. It also features ground fault protection, overcurrent protection, and electric shock protection.
