category : Zinc oxide arrester live tester
The YHX-C microcomputer zinc oxide lightning arrester detector is a special instrument for on-site live measurement and laboratory detection of the electrical performance of lightning arresters. The main purpose is to measure the resistive current of MOA, thereby judging the degree of moisture and aging of MOA. The instrument is suitable for live or power-off detection of zinc oxide lightning arresters of various voltage levels in AC and DC systems. The instrument uses a microcomputer for calculation and processing, and the measurement process is entirely controlled by the microcomputer. In the AC system, the full current, resistive current (peak value), capacitive current (peak value), active power and test voltage of the zinc oxide lightning arrester can be measured. Instrument working mode: Using the PT secondary voltage as a reference (secondary method) to decompose the leakage current of MOA into resistive current and capacitive current. When MOA is damp or aged, the resistive current component in its leakage current increases significantly. In the DC experiment, the full current of the zinc oxide lightning arrester can be measured. The output mode is a large-screen LCD display with backlight, which displays all the measured data at once, and can be clearly observed during the day and night. And it has a printing function. Print the measured data in real time. The instrument has the characteristics of simple operation, high measurement accuracy and good reliability.
