Online circuit breaker monitoring system

Circuit breakers are used in a power system to break or make current flow through\npower system apparatus. Reliable operation of circuit breakers is very important to the\nwell-being of the power system. Historically this is achieved by regular inspection and\nmaintenance of the circuit breakers. An automated online circuit breaker monitoring\nsystem is proposed to monitor condition, operation and status of high and medium\nvoltage circuit breakers. By tracking equipment condition, this system could be used to\nperform maintenance only when it is needed. This could decrease overall maintenance\ncost and increase equipment reliability. Using high accurate time synchronization, this\nsystem should enable development of system-wide applications that utilize the data\nrecorded by the system. This makes possible tracking sequence of events and making\nconclusions about their effect on-line. This solution also enables reliable topology\nanalysis, which can be used to improve power flow analysis, state estimation and alarm\nprocessing.
