| Abstract: | High voltage breaker plays an important role in the security of an electric power system. Online monitoring of high voltage breaker helps improve the system reliability. In this paper items to be monitored are first introduced, and then based on DSP and CPLD, a system which can monitor these items online is given, The principles and functions of each part of the system such as the sensors, DSP, A/D converter, multiplexer, CPLD, communication port etc. are described in detail, Owing to its capability of signal processing, the DSP in the system can accomplish complex failure diagnosis, thus it provides a good hardware platform for online monitoring of the operation of high voltage breaker. |
