Product Description
Product Overview
The XHDD405 Wireless Series Zinc Oxide Arrester Live Tester is suitable for live or power-off testing of zinc oxide arresters at all voltage levels. It can timely detect hidden dangers such as internal insulation dampness and valve plate aging.
It can measure total current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference. The large screen displays real voltage and current waveforms, and accurately analyzes the content of fundamental wave and 3rd to 7th harmonics.
Performance Features
★ Adopts high-precision sampling technology and Fourier harmonic analysis;
★ High-speed magnetic isolation digital sensor directly collects voltage and current input signals;
★ Replaces PT secondary wiring with electric field induction or wireless transmission;
★ Provides six kinds of test methods;
★ Supports resistive current fundamental peak output and side-phase correction;
★ Built-in battery, calendar clock and micro printer; stores up to 120 groups of test data.
