ZLCD***1 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 arresters 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.
Features:
I. **0×**0 color LCD touch
panel, high speed thermal printer; photo and context display and
intuitive interface, it is easy for onsite operation and use.
II. Wireless transmission PT signal
is over **0 meters,if special requirement configuration, can up to
***0 meters.
III. It is suitable and used for arrester
with power、no power and lab room and so on please.
IV. Really do 3 phases current and 3 phases
voltage testing at the same time, improve working efficiency;
Instrument only bring weak power internally, voltage is no more
than *2V; Current、voltage sensor is totally quarantined,safe and
firmly.
V. Supports both wire
synchronization、wireless sync voltage reference signal
sampling;also supports no voltage method, find voltage reference by
software calculation.
VI. Select equipped high power lithium ion
battery, very helpful for no power place. Instrument only have weak
electric.
VII.Equipped with embedded industrial grade operating
system, support direct shut down method; equipped one USB port,
support U disk export data; can plug external USB mouse、keyboard ,
easy operation.
VIII. Internal equipped 4G capacity SD card
can store big volume data, and have data management、storage
function and so on.
IX. Equipped superior management
software,have historical data management、data analysis、report
printing function and so on.
X. High speed sampling frequency,advanced
digital signal process technology,strong anti-interference ability,
super high accuracy of testing result.
