Abstract: A method and system for monitoring condition of a fleet of circuit breakers includes: measuring at least one type of operating condition related signal for the respective circuit breakers during their operation; obtaining a set of feature data representing the respective measurements of operating condition related signal; performing cluster analysis of the set of feature data based on a similarity threshold; and generating a signal indicating the condition of the fleet of circuit breakers based on the resulting cluster number. Rather than comparing the data representing the measurements of operating condition related signal to a reference model built on CB's normal data, the method includes applying cluster analysis of the set of feature data representing the respective measurements of operating condition related signal. The method does not need a reference “normal” database for comparison.

Abstract: A method for monitoring a circuit breaker and an apparatus and an internet of things using the same. The method includes: obtaining a first data set representing force applied to a fixed point of an element of an actuating mechanism of the circuit breaker in present operation cycle, judging a health condition of the circuit breaker in consideration of normal operating condition related parameters of the element according to a history profile when the circuit breaker operated normally and current operating condition related parameters of the element in the present operation cycle extracted from the force represented by the first data set, and generating a signal indicating the health condition of the actuating mechanism of the circuit breaker. The force applied to the fixed point of the actuating mechanism of the circuit breaker, which corresponds to a health condition of mechanical parts of the circuit breaker as a whole, is selected as an indicator for condition monitoring of the mechanical parts of the circuit breaker. The operating condition related parameters derived from the measurements of the force are considered giving a relatively high accurate judgement of the whole mechanical parts of the circuit breaker.
