Overview zinc oxide arrester tester is a special instrument used to test the electrical performance of zinc oxide arrester. The instrument is suitable for live or power failure detection of zinc oxide arrester of various voltage levels so as to timely detect the internal insulation damp and valve aging and other dangerous defects. zinc oxide arrester tester is easy to operate and easy to use. The whole measuring process is controlled by single chip microcomputer. It can measure the total current resistive current and its harmonics power frequency reference voltage and its harmonics active power and phase difference. The instrument uses digital waveform analysis technology harmonic analysis and digital filtering software anti-interference methods to make the measurement results accurate and stable. Parameter: 1.

Product description The metal oxide arrester tester is used for the measurement and analysis of metal oxide arrester MOA leakage. It is mainly used for measuring the resistive current to analyze the degree of zinc oxide aging and damp. The field charged test shall conform to Electric Power Industry Standard of the People's DL474.5-92 Guide for Insulation Test on Site - Lightning Arrester Tests. The metal oxide arrester tester can be also used for factory and acceptance tests. Zinc oxide arrester tester Technical Indexes Range of reference voltage input peak 10V-200V Measurement range of full leakage current peak 100uA 10mA Measurement range of resistive current peak 100uA 10mA Measurement range of capacitive current peak 100uA 10mA Measurement range of angle 0-90 Power consumption 4W System measurement accuracy reading 5 5 words not more than 2m for harmonic current AC power supply AC 220V 10 50Hz 1 Precautions When measure the reference voltage from PT or the measuring end of the testing transformer, carefully check wiring to avoid the PT secondary or test voltage short circuit. Be careful not to wrongly connect the current and voltage sampling lines in the connecting process. In the laboratory experiment, the high voltage power supply cannot use the series excitation testing transformer.
