Product introduction

NABLC-III zinc oxidearrester detector is a special instrument for detecting electricalproperties of zinc oxide surge arresters. The instrument issuitable for charging or power outage detection of various voltagelevels of zinc oxide surge arresters, timely detection of e insulation damp and valve aging and other dangerousdefects.

NABLC-III zinc oxidearrester detector is simple and easy to operate, the entiremeasuring process is controlled by microcontrollers to measure thefull current, resistive current and its harmonics, fre voltage and its harmonics, active power and phasedifference of zinc oxide surge arrester, a large screen can displaythe real waveform of voltage and current.

The instrument is adopt with digitalwaveform analysisues, used harmonic analysis and digitalfiltering software such as anti-jamming method to make the testresult accurate and stable, it not only can accurately analysis thefundamental and the content of 3 to 7 times of harmonic, but alsocan overcome the influence of the interphase interference torightly measuring the resistive current of edge phasearrester.

The instrument is e withhigh-speed printer panel, rechargeable battery, it is veryconvenient to test in the field. It uses a unique high-speedmagnetic isolation digital sensor to directly collect the signal ofinput voltage and current, ensure the data reliability andsecurity.

Product information

1, Taken from the PT secondary voltagereference, you should carefully check the wiring to avoid PTsecondary circuit.

2, The voltage signal input line and thecurrent signal input line must not be reversed, if the currentsignal input line connected to PT3, test transformer secondary sideor measuring end, it may burn the instrument.

3, Where the input voltage and inputcurrent circumstances, do not plug the measuring line, so as not toburn the instrument.

4, The instrument is damaged, stop usingit immediately and notify the Company and do not repair yourselfout of the box. When the instrument is not working properly, firstcheck the power fuse is blown. After replacement of the same modelcan continue the insurance experiment. If the problem is morecomplex, please contact me directly.

5, The instrument must not be placed inhumid and high temperature environments.

6, The instrument is not used as a longtime (more than three months), the battery will run out of damage,so each interval of 3 months should be given to the instrument onecharge (6 hours or more), in order to ensure that the instrumentcan be used normally. Charging steps: Turn the power switch, plugin 220V power until the battery is indicating below the LCD screen90% or more.
