Introduction
GOZ-YB-2007 metal oxide arrester charged tester is mainly used for the detection of AC electrical parameters of charged metal oxide arresters. The instrument voltage sampling method is: Voltage transformer (or test instrument transformer winding) voltage signal is through fused voltage test line to connect access channel, as the reference voltage signal. Current sampling methods: Current channel is the core of the built-in current sensor type with small signal distortion. GOZ Technology can meet requirements like China State Grid Electricity Power Research Institute and other relevant authorities' inspection, and issue a metal oxide arrester charged test report.
Also called: Metal oxide arrester tester, intelligent metal oxide arrester tester, anti-interference metal oxide arrester tester, arrester resistive leaking current tester, AC gapless metal oxide arrester tester, metal oxide arrester feature tester

4. With a high-energy lithium-ion battery, especially suitable for non-power applications.
5. Truely three-phase measurements, three phase current input channels with 2mA and 10mA two stalls to choose;
6. Module power supply, reserved interface, support for high-precision micro-current clamp sensor interface.
7. Feature data, waveform screen display;
8. Multiple voltage reference signal sampling method: 1) wired way: Take winding signal, digital signal transmission; 2) wireless way: Winding take signals, digital signals from the wireless transmission, eliminating long distance cable connection; 3) no voltage mode: Do not take the signal from the terminal PT, by way of software to calculate the voltage reference standard.
9. Safe and reliable, the use of isolation voltage channel transformation, PT secondary side short circuit avoided, reducing the signal distortion.
10. Charged, power failure and laboratories can be applied.
11. Small size, light weight, easy to carry.
