Patent number: 11867763Abstract: 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.Type: GrantFiled: December 29, 2020Date of Patent: January 9, 2024Assignee: ABB SCHWEIZ AGInventors: Jiayang Ruan, Niya Chen, Rongrong Yu

Publication number: 20220018707Abstract: Methods for monitoring a circuit breaker include detecting at least one operation of a circuit breaker to obtain at least one vibration signal of the circuit breaker. Each vibration signal is represented as one-dimensional data of a vibration amplitude over time during the operation of the circuit breaker. The vibration signal is transformed to two-dimensional frequency-time data. The transformed frequency-time data is compared with benchmark data characterizing the at least one operation of the circuit breaker. A health condition is determined of the circuit breaker at least in part based on the comparison. Both the frequency component and the time component in the detected test vibration signals are considered in condition determination of the circuit breaker. The condition can be determined with high accuracy.Type: ApplicationFiled: December 24, 2018Publication date: January 20, 2022Applicant: ABB Schweiz AGInventors: Niya Chen, Jiayang Ruan
