HPYZ-301 Leakage Current Tester Zinc Oxide Lightning Arrester Characteristic Tester

I. General information

Lightning Arrester Tester is the special equipment of testing zinc oxide arrester electric performance. It is suitable for testing various voltage levels zinc oxide arrester with or without electricity, thus to detect hazards inside the device caused by wet insulation or metal oxide varistor (MOV) aging.

II. Features

1. 800*480 color LCD touch screen, with high speed thermal printer.

2. Graphic display, intuitive interface, easy to operate and use on-site.

3. Long distance wireless transmission. PT signal wireless transmission distance more than 400m (2000m can be customized).

4. Suitable for testing in various situation such as lightning arrester with or without electricity, laboratory.

5. Test three phase current, three phase voltage at the same time, more efficient.

6. No strong electricity inside, voltage not more than 12V. Current and voltage sensors are completely isolated, safe and reliable.

7. Support various voltage sampling: 1. Wired; 2 wireless; 3. Non-voltage;

A. Wire: digital signal transmission with cable which the signal is from PT metering winding;
B. Wireless: digital signals wireless transmission which the signal is from PT metering winding;
C. Non-voltage: no need to get signal from PT terminals. Use software calculation to get voltage standard.

8. Built-in high capacity Li-battery, suitable for no power supply field.

9. Adopts embedded hardware platform and embedded operating system, it can expand audio and video playback functions and game entertainment functions.

10. The instrument can be switched on and off at any time, which is more stable than the instrument with industrial computer as hardware platform, and is not easy to crash and system collapse.

11. Equipped with a USB port to support the export of data from U disk.

12. Built-in 4GB SD card, can store massive test data, and has functions such as data management and storage.

13. High speed sampling frequency, advanced digital signal processing technology, strong anti-interference performance, high precision measurement results.

14. With dust-proof, waterproof, anti-corrosion plastic sealed box, small size, light weight, easy to carry.
