Zinc Oxide Lightning Arrester Tester

Zinc Oxide Lightning Arrester Tester 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.

It 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.

It 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.

It 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.
