KDYZ-301 Zinc oxide lightning arrester live tester (lightning arrester online detector) for zinc oxide [MOA] leakage current measurement and analysis. It is mainly used to measure resistive current, 3-7 harmonic current, so as to analyze the degree of aging and moisture of zinc oxide. It is a special instrument for testing various AC electrical parameters in the operation of zinc oxide arrester, and can also be used in the laboratory to make factory and acceptance tests.

Instrument features:
1. A variety of voltage reference signal sampling methods:
Wired synchronization: the signal is taken from the PT end metering winding, and the digital signal is transmitted wired.
Wireless synchronization: From the PT end metering winding B phase signal, digital signal wireless transmission, eliminating the cable long distance connection.
Induction board synchronization: do not need to take signals from the PT terminal, install induction board from the zinc oxide arrester B phase base to take voltage signals.
No voltage synchronization: It does not need to obtain signals from the PT terminal, and uses software calculation to find the voltage reference.
2. Voltage and current signals (input impedance less than 1Ω) are isolated to ensure data reliability and security.
3. The instrument can be measured three times and calculate automatically without compensation.
4. Ac, DC dual-purpose, with high energy lithium-ion battery, especially suitable for no power occasions.
5. Supporting host computer software can survive word report, convenient data management and query;
6. Survival word report can intuitively tell you the quality of zinc oxide arrester.
7. The instrument is controlled by a small computer, equipped with 800×480 color LCD touch screen, high-speed printer, support external mouse, easy to operate;
8. 1000 sets of data can be automatically saved inside the instrument, and can also be stored with external U disk.
