GOZ-YB-2007 Metal Oxide Arrester Charged tester
GOZ-YB-2007 mental oxide arrester charged tester is mainly used for the detection of AC electrical parameters of charged mental 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 mental oxide arrester charged test report.
Also called: mental oxide arrester tester, intelligent mental oxide arrester tester, anti-interference mental oxide arrester tester, arrester resistive leaking current tester, AC gapless mental oxide arrester tester, mental oxide arrester feature tester
