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 (charger built-in):
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 the power icon indicator to see if it is fully charged. During use, the battery icon indicator reflects the battery level.
Wireless current clamp charging method:
Use the included charger to charge. It is required to charge for more than 1 hour in the off state. After fully charged, you can see the charger's red light turn green. During use, if the power indicator is constantly on, it means the battery is normal; if the power indicator blinks or is off, it means the battery is low.
