| Abstract: |
| The principle of bus-based online resistive leakage current monitoring of 750 kV MOA is presented，which is designed with the singlechip and programmable CAN controller，including the functional modules of signal collection，site measuring，bus communication and expert system. The site measuring and transmission of data are implemented by the sensor，signal processing unit and CAN bus，while the data inquiry，diagnosis and alarm functions are implemented by the algorithms based on expert system. The remote monitoring of 750 kV MOA with site measuring and data transmission is achieved and its effectiveness is verified by excellent site operation. |
