Lightning Arrester And Insulator Tester

RDYZ-II Arrester Counter Tester is a special instrument for detecting the discharge counter at the lower end of arrester in substations, hydro thermal power plants and large self provided power plants. The Discharge Counter Detector can not only check the number of lightning strokes, but also check the leakage current.

RDYZ-302 Metal Oxide Surge Arrester Analyzer is a special instrument designed for live detection of metal oxide arrester in power system. It can measure the AC leakage parameters of the equipment in the running state, so as to timely find out the dangerous defects such as moisture in the internal insulation of the equipment and the aging valve plate. By accurately sampling the voltage and current signals of the measured equipment, the instrument adopt anti-interference methods such as Fourier transform technology, harmonic analysis and digital filtering to make the measurement results accurate and reliable.

RDYZ-301 Metal Oxide Surge Arrester Analyzer is a dedicated and specialized to verify the electrical specifications of Zinc Oxide Arrester.TheZinc Oxide Arrester Tester is applicable for various kinds of voltage classes of zinc oxide arrester online and offline testing.Thus detect the risk and flaw of inner insulation mositure and valve aging.
RDYZ-301 Metal Oxide Surge Arrester Analyzer is very easy operation, convenient using. IPC controls all measuring process. The Surge Lightning Arrester can measure whole current, resistive current and its harmonic wave, frequency reference voltage and its harmonic wave, active power and phase difference. Voltage and current waveform can be clearly showing on the screen.
The MOA Tester adopts digital analysis waveform techniques, harmonic waveform analysis and digital filtering software anti-interference method to ensure accurate and stable measurement. The MOA Tester can analyze the content of fundamental wave and 3 to 7 times harmonic wave. The MOA Tester overcomes interphase interference, accurately measure the resistive current of side phase arrester.
