Why Zinc Oxide Arrester Tester is Popular Among Power Workers - Yangzhou Darui

Darui Electric recommends for you



 Power workers working in substations generally prefer the zinc oxide arrester tester. They all like this device, which is mainly used to test zinc oxide arresters and judge the insulation performance of zinc oxide arresters. So why is the zinc oxide arrester tester popular among power workers? This article will give you a brief introduction.



 Zinc oxide arrester tester is an instrument used to detect the electrical performance of zinc oxide arresters. It is suitable for on-site or outage testing of zinc oxide arresters of various voltage levels, and can timely discover dangerous defects such as internal insulation moisture and valve plate aging.

        The instrument is simple to operate and easy to use. The entire measurement process is controlled by a single-chip microcomputer, measuring total current, resistive current, harmonics, power frequency reference voltage and harmonics, measuring the active power and phase difference of zinc oxide arresters, and displaying the true waveforms of voltage and current on a large screen. The instrument adopts digital waveform analysis technology, and uses anti-interference methods such as harmonic analysis and digital filtering to make the measurement results accurate and stable, and can accurately analyze the content of fundamental waves and 3-7th harmonics, overcome the influence of phase-to-phase interference, and correctly measure the resistive current of side-phase arresters. This machine is equipped with a high-speed panel printer and rechargeable battery, making it very convenient for testers to use on site. The instrument uses a unique high-speed magnetic isolation digital sensor to directly collect input voltage and current signals, thereby ensuring the reliability and safety of data.

        Main features of zinc oxide arrester tester:

        1. This machine adopts a large-screen LCD display, full Chinese menu operation, and is easy to use.

        2. High-precision sampling, processing circuit, and advanced Fourier harmonic analysis technology ensure more reliable data.

        3. The instrument uses a unique high-speed magnetic isolation digital sensor to directly collect input voltage and current signals, ensuring the reliability and safety of data.

        4. The instrument can be used to replace the electric field of the induced PT secondary wiring method.

        5. No-voltage mode, no need to use PT secondary voltage signal, and find the voltage reference value through software calculation.

        6. The same instrument can measure three phases, with automatic compensation. It is especially convenient.

        7. It has functions such as resistive current fundamental peak output and side phase correction.

        8. The instrument is equipped with a rechargeable battery, calendar clock, and micro printer, and can store 120 sets of measurement data.

        The zinc oxide arrester tester is popular among the majority of power workers because it is convenient to test zinc oxide arresters and has relatively high accuracy, which is not surprising.
