“…New methods of CB diagnosis have to be developed to increase the reliability of CB operation and to lower the power substation maintenance costs. The use of non-electrical signal for CB diagnosis was described elsewhere [1]. The present paper focuses on the architecture of the information system used for CB diagnosis and on the methods of the analysis of the CB electrical signals.…”

E-diagnosis in the context of power industry means conducting remote, on-line diagnosing of electrical equipment with the use of several technologies like distributed data processing, distributed databases and modern communication protocols. In the paper the concept of e-diagnosis of switchgear equipment that separates spatially raw data acquisition, data processing and data storage has been described. While systems for remote diagnosing the Circuit Breaker condition with data processing going on in dedicated data concentrators have been known for some time, the e-diagnosis system described in the paper uses IEC 61850 standard for data transmission and SQL databases with remote access for computed data exchange. Distributed intelligence in the system makes it Smart Grid like. In the paper detailed algorithms and techniques for CB signals parameters extraction have also been presented.Index Terms-circuit breaker, expert systems, power system protection, signal analysis,
