Cheap Price Wireless Zinc Oxide Lightning Arrester
Tester Three Phase Surge Arrester Test SetProduct introductionThe
instrument is used for detection of different voltage levels Zinc
Oxide arresters power on or off. The inner damping, valve aging and
other dangerous defects will be found timely. The instrument can
test the full current, resistive current and harmonic, 50HZ
reference voltage and harmonic, active power and phase difference
of the ZnO arrester. The real waveform can display on the large
screen.Adopted digital waveform analysis technology, harmonic
analysis and digital filter software, the instrument can accurately
measure the content of principle wave and 3-7 times harmonic. Also
it can measure the resistive current avoiding the interference of
interphase.Features:1. Wireless transmission PT
signal more than 1000 meters2. Suitable for
arrester live , off power or lab3. Three-phase
current, three-phase voltage test at same time, more
efficient;4. Two kinds of sampling method of
voltage reference signal: wired synchronism and wireless
synchronism5. Anti-jamming performance, high
accuracy.6. 7'color LCD touch screen, high speed thermal printer,
display of graph and test, nice operational
interface.7 Big capacity Lithium battery,
portable design8. Equipped with bluetooth
interface, many protocols to access to the
internet.9. Supporting PC management software,
with historical data management, data analysis, report printing and
other functions.Technical specification Measurement
