Product introduction

NABLC-III zinc oxide arrester detector is a special instrument for detecting electrical properties of zinc oxide surge arresters. The instrument is suitable for charging or power outage detection of various voltage levels of zinc oxide surge arresters, timely detection of equipment internal insulation damp and valve aging and other dangerous defects.

NABLC-III zinc oxide arrester detector is simple and easy to operate, the entire measuring process is controlled by microcontrollers to measure the full current, resistive current and its harmonics, frequency reference voltage and its harmonics, active power and phase difference of zinc oxide surge arrester, a large screen can display the real waveform of voltage and current.

The instrument is adopt with digital waveform analysis techniques, used harmonic analysis and digital filtering software such as anti-jamming method to make the test result accurate and stable, it not only can accurately analysis the fundamental and the content of 3 to 7 times of harmonic, but also can overcome the influence of the interphase interference to rightly measuring the resistive current of edge phase arrester.

The instrument is equipped with high-speed printer panel, rechargeable battery, it is very convenient to test in the field. It uses a unique high-speed magnetic isolation digital sensor to directly collect the signal of input voltage and current, ensure the data reliability and security.

Product information

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

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

3, Where the input voltage and input current circumstances, do not plug the measuring line, so as not to burn the instrument.

4, The instrument is damaged, stop using it immediately and notify the Company and do not repair yourself out of the box. When the instrument is not working properly, first check the power fuse is blown. After replacement of the same model can continue the insurance experiment. If the problem is more complex, please contact me directly.

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

6, The instrument is not used as a long time (more than three months), the battery will run out of damage, so each interval of 3 months should be given to the instrument one charge (6 hours or more), in order to ensure that the instrument can be used normally. Charging steps: Turn the power switch, plug in 220V power until the battery is indicating below the LCD screen 90% or more.
