ZLCD-301 zinc oxide arrester with electric testing instrument is dedicated and used to verify electric performance of zinc oxide arrester，it is suitable for all kinds of voltage level zinc oxide arrester with and without electric testing, thus detect moisture inside the device and valve insulation aging and other dangerous defects.
 

Instrument is easy to operate and use，microcomputer control the whole process，can measure zinc oxide arrester’s full current、resistive current and its harmonic wave、power frequency reference voltage and harmonic wave、active power and phase difference, big screen can display real waveform of voltage and current. Instrument is using digital wave analysis technology，adopts harmonic analysis and digital filtering and so on software resisting interference method which makes testing result to be accurate、stable，can analyze accurately fundamental wave and 3 ~7 harmonic content，and can overcome the impact of interference between phases, correctively measure resistive current of side phase arrester.

I.     800×480 color LCD touch panel, high speed thermal printer; photo and context display and intuitive interface, it is easy for onsite operation and use.
