“…Moreover evidential reasoning generates the overall assessment of the circuit breaker condition. A framework to assess the circuit breaker condition using the control signal waveforms was presented in [22]. The authors use classification techniques to categorize the health of the circuit breakers with qualitative (normal, alarm and emergency) and probabilistic quantitative indices.…”

Abstract-Prognostics predictions estimate the remaining useful life of assets. This information enables the implementation of condition-based maintenance strategies by scheduling intervention when failure is imminent. Circuit breakers are key assets for the correct operation of the power network, fulfilling both a protection and a network reconfiguration role. Certain breakers will perform switching on a deterministic schedule, while operating stochastically in response to network faults. Both types of operation increase wear on the main contact, with high fault currents leading to more rapid ageing. This paper presents a hybrid approach for prognostics of circuit breakers, which integrates deterministic and stochastic operation through Piecewise Deterministic Markov Processes. The main contributions of this paper are (i) the integration of hybrid prognostics models with dynamic reliability concepts for a more accurate remaining useful life forecasting and (ii) the uncertain failure threshold modelling to integrate and propagate uncertain failure evaluation levels in the prognostics estimation process. Results show the effect of dynamic operation conditions on prognostics predictions and confirm the potential for its use within a condition-based maintenance strategy.

Smart grid is developing rapidly with the promotion of artificial intelligence (AI) technology, and online condition assessment of circuit breaker (CB), as one of the most important facility in power system, is increasingly requested. Owing to most of CB faults can be reflected on its coil current (CC), lots of papers research on the relationship between CC data and CB fault. This paper proposed a new method to get distinctive CC feature set, which achieves better data distinction and has more practical physical meaning. The classification experiments based on the new feature set show that the proposed method can quickly and accurately recognize fault, meanwhile point out the malfunctioning device.

“…Traditionally, CBs have been maintained based on a scheduled maintenance scheme (time-based maintenance). However, it may result in unnecessary involvement and expenses, or even generate defects during the overhauling of CBs [5][6][7][8]. To significantly enhance a cost-saving maintenance and improve the system reliability, online and automatic CB diagnostics are recognized as being a key solution.…”
