| Abstract: | The working principle and the defects in practical application of residual current disposition module of seperated residual current circuit breaker were analyzed, and a disposition method of residual current was proposed based on real-time sample of single chip microcomputer. Its hardware principle and software flowchart were given. Tests show this method is stable, reliable and accurate, and can be a guidance for the design of residual current circtui breaker in fieldbus. |
