タイトルまたは説明

HYG-III/IV zinc oxide arrester testing with electric instrument is dedicated and used to detect electric performance of zinc oxide arrester. It is suitable for all kinds of voltage level zinc oxide arrester with power or power off testing, thus detect the dangerous errors and so on of equipment internal insulation wet and valve block aged.
 
Instrument is easy operation, convenient use, and whole testing process is controlled by microcomputer. It can measure full current, resistive current and harmonic wave, power frequency reference voltage and its harmonic wave, active power and phase difference of zinc oxide arrester, 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.
 
Product Features:
1. Instrument standard configure do not include high power lithium ion battery, but can select internal equipped one.
2. 5.7 inch **0×**0 LCD screen, high speed thermal printer; photo and context display and intuitive interface, it is easy for onsite operation and use.
3. It is suitable and used for arrester with power, no power and lab room and so on please.
4. Current and voltage sensor is totally quarantined, safe and reliable. Separated 3 times testing of A, B, C 3 phases zinc oxide arrester can stored into as one set testing data.
5. Instrument can do test consecutively, display voltage and current curve and quick printing data and curve.
6. Internal equipped memory, can store **0 sets testing data with power off.
7. Select equipped RS**2 communication connector, can do test by upper computer and extract testing data.
8  Can do anti-interference calculation, to offset current of phase A, phase C from the deviation of B phase.
