The NRBLC-IV three-phase zinc-oxide arrester tester is a special instrument used to test the electrical performance of zinc-oxide arresters. The instrument is applicable to the live or power failure detection of zinc oxide arrester with 35kV ~ 500kV voltage level, so as to timely find dangerous defects such as damp insulation inside the equipment and aging of valve plate.
Overview
Functions
The NRBLC-IV zinc-oxide arrester tester is simple to operate and easy to use. The whole measurement process is controlled by a single-chip microcomputer. It can measure the full current resistive current and its harmonics power frequency reference voltage and its harmonics active power and phase difference the large screen can display the true waveforms of voltage and current. The instrument uses digital waveform analysis technology and uses software anti-interference methods such as harmonic analysis and digital filtering to make the measurement results accurate and stable. It can accurately analyze the content of the fundamental wave and the 3rd to 7th harmonics and can overcome the influence of interphase interference. Measure the resistive current of the side-phase arrester. This machine is equipped with a high-speed panel printer and a rechargeable battery. It is very convenient for testers to use on site. The instrument uses a unique high-speed magnetically isolated digital sensor to directly collect the input voltage and current signals to ensure the reliability and safety of the data.
