Product Description

Hengfeng zinc oxide lightning arrester leakage current monitor can measure condition while a surge arrester is still in service, measuring the quality of the metal oxide blocks and helping manage the risk of failure.

A surge arrester may be inexpensive, but it has an important role in protecting your transformers.

With surge arrester test set, it takes less than 2 minutes to establish that your surge arresters are healthy and the transformer is still protected.

It can measure the full current, resistive current and harmonics, power frequency reference voltage and harmonics, active power and phase difference. The real waveform of voltage and current can be displayed on the large color screen. It can accurately analyze the content of fundamental wave and third to seventh harmonics, overcome the influence of inter-phase interference, and correctly measure the resistive current of side-phase arrester.

Features

1. Rated in accordance with IEC 60099-5 for field monitoring of metal oxide surge arresters

2.Portable, rechargeable battery-operated instrument for regular condition assessment of surge arresters.

3. 7 inch corlor touch screen with stylus pen.

4. High-precision sampling and processing circuit, advanced Fourier harmonic analysis technology to ensure more reliable data.

5.Adopt unique high-speed magnetic isolation digital sensor to directly collect the input voltage and current signals, which ensures the reliability and safety of the data.

6. Either single-phase test or three-phase measurement is available.

7. This MOA tester can use electric field induction instead of PT secondary wiring.

8. If the secondary voltage of PT is not connected, the instrument directly measures the resistive current.

9. In three - phase test, the instrument has automatic compensation function.

10. Three-phase voltage and three-phase current are collected and displayed at the same time.

11. It can directly measure the resistive current, also can use harmonic method to test the resistive current.

12. The test results show voltage, full current, and resistive current curves.

13. lightning arrester tester can automatically judge the aging degree of zinc oxide arrester.

14. Internal thermal printer

15. Zinc oxide lightning arrester characteristic tester can store 1000 sets of data in internal memory.

16. USB interface

17. RS232.

18. PC software is available.
