An overview,
ZY8500 Zinc oxide arrester resistive current tester, is a special instrument designed for electric power system metal oxide arrester charged detection. It can measure the resistive leakage current of the equipment in the running state, so as to timely find the dangerous defects such as dampness of the internal insulation and aging of the valve plate. The instrument accurately samples voltage and current signals of the tested equipment, and uses Fourier transform technology, harmonic analysis and digital filtering to make the measurement results accurate and reliable.
