An on-line monitoring system is constructed through developing two kinds of UHF sensors
designing a pattern recognition unit based on AGA-BP neural network algorithm
coding a program to control the system and display
and adopting the signal modulating technique based on frequency mixing.The system performance is verified with the experiments of partial discharge in transformer and GIS.
