Ultra High Voltage(UHV)transmission technology , which is an international leading technology independ -ently developed in China, is an important part of the future power grid construction .It plays an important role in the country's future power grid construction and smart grid strategy to promote the research on the intelligent UHV trans -mission line inspection equipment and its engineering applications .The intelligent detector for the UHV alternating porcelain insulator with the ARM Cortex -M4 processor as the core was designed to examine and repair the UHV transmission lines.The detector, whose main function was to detect the low value and zero value of the porcelain insu -lator, consisted of micro -controller, insulator resistance measuring module , insulator video detecting module, man -machine interface , storage system and PMS system interface.The detector was designed based on the concrete operat -ing requirements of the UHV power line tower site staff.The judgment of the low zero value was made according to the impedance of the insulator.The detector could meet the need of the UHV transmission lines for the insulator ’s low ze-ro value measurement, and the measurement error was less than 3%, which was better than the measurement accuracy of 5% ~10% of the existing UHV insulator detectors.
