The Zinc Oxide Arrester Comprehensive Tester is used to check the electrical performance of zinc oxide arresters (MOAs). This instrument is suitable for on-site inspection of zinc oxide arresters at all voltage levels, as well as for factory testing and acceptance testing in the event of a power failure. By measuring parameters such as total current, resistive current, and others, it is possible to detect dangerous defects, such as internal insulation issues and valve aging in the zinc oxide arrester. Functions And Fearutres 1 .Being miniaturized and hand-held, small in size, and light in weight, the instrument is easy to carry and operate. 2. Using a high-performance, low-power ARM processor with DSP floating-point processing units, the computing speed is faster, the operation accuracy is higher, and the data processing capacity is larger. This ensures the accuracy and stability of the test data. 3 .The high-precision sampling filter circuit and digital filter technology can filter out interference signals from the environment. 4 .The floating-point fast Fourier algorithm is used to achieve high-precision analysis of the fundamental wave, harmonic voltage, and current signals. 5 .Using an industrial-grade 5.6-inch, 640 × 480 dot matrix high-brightness color LCD screen, the display is clear and provides a user-friendly interface. For important operations and parameter settings, the system displays tips and help instructions. The top of the screen’s status bar shows information on the working status of each peripheral and the test status.
