Abstract: It provides a method for monitoring condition of a fleet of circuit breakers and a system and an internet of things using the same. The method includes: (a) measuring at least one type of operating condition related signal for the respective circuit breakers during their operation; (b) obtaining a set of feature data representing the respective measurements of operating condition related signal; (c) performing cluster analysis of the set of feature data based on a similarity threshold; and (d) generating a signal indicating the condition of the fleet of circuit breakers based on the cluster number resulted from the step (c). 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 applies cluster analysis of the set of feature data representing the respective measurements of operating condition related signal, does not need a reference "normal" database for comparison.
