The Austrian three high Electrical Equipment Co., Ltd. Wuhan Wei - WAYH-V-type three-phase zinc oxide arrester tester Overview: zinc oxide arrester tester is a dedicated instrument for the detection of zinc oxide surge arresters electrical performance. The instrument is suitable for various voltage levels of zinc oxide surge arresters charged or power outage detection, and thus the risk of defects to detect the device's internal insulation damp and aging of the valve plate. The instrument is simple, easy to use, measure the whole process is controlled by a microcontroller, measurable the MOA current resistive current and its harmonics, power frequency voltage, active power and phase difference. The large screen can display the real voltage and current waveforms. Instrument using digital waveform analysis technology, using harmonic analysis and digital filtering software such as anti-jamming method the measurement results accurate, stable and accurate analysis of the fundamental and 3 to 7 times the harmonic content, and to overcome the interference and white, resistive current measurement edge phase arrester. The instrument uses a unique high-speed magnetically isolated digital sensors, direct acquisition of the input voltage and current signals, ensure data reliability and security. The instrument is equipped with high-speed panel printer, rechargeable battery, testing personnel in the field is very convenient to use. Instrument features: 1, three-phase resistive current arrester simultaneous measurement. 2 current measurement MOA, resistive current and its harmonics, frequency voltage, active power and phase difference. 3, the apparatus is capable of interference, automatic compensation function. 4, with a the resistive current fundamental peak output, edge correction and other functions. 5, large-screen LCD display, full Chinese menu, easy to use. 6, the apparatus is equipped with a rechargeable battery, calendar, clock, mini printers. 7, can be stored measurement data.
