The zinc oxide arrester live tester is simple to operate and convenient to use. The entire measurement process is controlled by a microcomputer. It can measure the fundamental, 3rd, 5th, and 7th harmonics of the total current of the zinc oxide arrester, the fundamental, 3rd, 5th, and 7th harmonics of the voltage, the fundamental, 3rd, 5th, and 7th harmonics of the resistive current, the positive peak of the resistive current, the negative peak of the resistive current, the capacitive current, active power, reactive power, and phase angle difference. The large screen can display the real waveforms of voltage and current. The instrument uses digital waveform analysis technology, and adopts software anti-interference methods such as harmonic analysis and digital filtering to make the measurement results accurate and stable. It can accurately analyze the content of the fundamental and 3rd to 7th harmonics, and can overcome the influence of inter-phase interference to correctly measure the resistive current of the side-phase arrester.
Correct charging method for zinc oxide arrester live tester
Main unit charging method (built-in charger):
Use the power cord to connect to AC220V/50Hz power supply. It is required to charge for more than 3 hours in the off state. After turning on, you can observe whether the power icon indicates full charge. During use, the battery icon indicates the remaining power.
Wireless current clamp charging method:
Use the supplied charger for charging. It is required to charge for more than 1 hour in the off state. After full charge, the charger's red light will turn green. During use, the power indicator light stays on to indicate normal power; if the power indicator light flashes or does not light up, it indicates insufficient power.
