Surge Arrester Tester

Product Overview

ED0403-IIThe Type Oxide Zinc Surge arrester Tester is a specialized instrument for testing the electrical performance of oxide zinc surge arresters. It is suitable for live or de-energized testing of oxide zinc surge arresters across various voltage levels, enabling the timely detection of dangerous defects such as internal insulation dampness and valve disc aging.

ED0403-IIThe Type Oxide Zinc Surge Arrester Tester is user-friendly with a simple operation. The entire measurement process is controlled by a single-chip microcomputer, capable of measuring the full current, resistive current and its harmonics, AC reference voltage and its harmonics, active power, and phase difference of the oxide zinc surge arrester. The large screen displays the true waveform of voltage and current. The instrument employs digital waveform analysis technology and utilizes software anti-interference methods such as harmonic analysis and digital filtering to ensure accurate and stable measurement results. It can accurately analyze the fundamental frequency and...3～7The device accurately measures the reactive harmonic content, overcoming inter-phase interference to correctly gauge the resistive current of the edge surge arrestor. Equipped with a high-speed panel printer and rechargeable batteries, the instrument is extremely convenient for field use by testers. The instrument utilizes a unique high-speed magnetic isolation digital sensor to directly collect input voltage and current signals, ensuring data reliability and safety.
