Using fuzzy logic for diagnosis of technical condition of power circuit breakers

Monitoring and diagnosis of power circuit breakers represent an important activity for increase the reliability and safety in power system. In order to deal with the uncertain information in the process of diagnosis, the paper presents a diagnosis system based on fuzzy logic which has the role to acquire information about the monitored equipment for faults detection. Also, the paper describe the LabVIEW software application based on fuzzy logic used for diagnosis of power circuit breakers which enable to generate alarms when something it is wrong with the electrical equipment.
