The paper introduces geoelectricity method and supersonic method commonly used for live detec-tion on partial discharge of 10~35 kV switch cabinets, and it analyzes merits and demerits of the two methods and the limitation of application. By use of geoelectricity method and supersonic method for field live detec-tion on partial discharge of switch cabinets, many faults of switch cabinets are detected, and the field appli-cation effect has been achieved. The paper indicates the development orientation of digital detection result analysis by digital signal and database establishment in the future.
