KDYZ-205 Zinc Oxide Arrester Resistive Current TesterProduct Introduction



KDYZ-205 Zinc Oxide Arrester Resistive Current Testeris produced and sold by Shanghai Xuji Electric Co., Ltd.



The KDYZ-205 Zinc Oxide Arrester Resistive Current Tester is a specialized instrument used to detect the electrical performance of zinc oxide arresters. This instrument is suitable for live or offline testing of zinc oxide arresters at various voltage levels, thereby promptly identifying dangerous defects such as internal insulation dampness and valve plate aging. The instrument is simple to operate and convenient to use. The entire measurement process is controlled by a microcontroller. It can measure the total current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power, and phase difference of zinc oxide arresters. The large screen can display the real waveforms of voltage and current. The instrument utilizes digital waveform analysis technology, employing harmonic analysis and digital filtering software anti-interference methods to ensure accurate and stable measurement results. It can accurately analyze the content of the fundamental wave and the 3rd to 7th harmonics. KDYZ-205 Zinc Oxide Arrester Resistive Current TesterDetailed Introduction
