Metal Oxide Surge Arrester Leakage Current Analyzer HFYH-8001B

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.
