Zinc Oxide Arrester Characteristic Tester is a special instrument for detecting the electrical performance of zinc oxide surge arresters.
The instrument is suitable for the detection of live or blackout of zinc oxide surge arresters of various voltage levels, so as to discover the dangerous defects such as internal insulation moisture and aging of the valve plate in time.
The instrument is simple in operation and easy to use. The whole process of measurement is controlled by a single-chip microcomputer and can measure the full current, resistive current and its harmonics, power frequency voltage, active power and phase difference of the zinc oxide arrester.
The large screen shows the true waveform of voltage and current.
The instrument uses digital waveform analysis technology and adopts software anti-jamming methods such as harmonic analysis and digital filtering to make the measurement result accurate and stable. The fundamental wave and the 3rd to 7th harmonics content can be accurately analyzed, and the influence of interphase interference can be overcome. Measure the resistive current of the edge arrester.
The instrument uses a unique high-speed magnetically isolated digital sensor to directly acquire the input voltage and current signals, ensuring the reliability and safety of the data.
The instrument is equipped with a high-speed panel printer, rechargeable battery, and the test personnel are very convenient to use in the field.
Performance characteristics:
1. Simultaneous measurement of three-phase arrester resistive currents.
2. Measure the full current, resistive current and its harmonics, power frequency voltage, active power, and phase difference of the zinc oxide surge arrester.
3, the instrument has anti-jamming, automatic compensation function.
4, with a resistive current fundamental peak output, side-phase correction and other functions.
5, large-screen LCD display, full Chinese menu operation, easy to use.
6, the instrument is equipped with a rechargeable battery, calendar clock, micro-printer.
7, can store measurement data.
