The zinc oxide arrester online tester is a special power testing instrument developed and produced by the electric power industry in accordance with the DL/T409-1991 power industry standard. It adopts advanced Fourier harmonic analysis technology, an embedded industrial control system, and multiple voltage reference signal sampling methods. It is AC/DC dual-use and has three-phase simultaneous measurement capability. The zinc oxide arrester online tester is suitable for live or de-energized testing of zinc oxide arresters of various voltage levels, thereby promptly detecting dangerous defects such as internal insulation moisture and valve plate aging.
