Switching devices are used in a wide application field to control and protect electrical
systems. Failures in such equipment cause a loss of reliability in electrical facilities, which …

Due to the untimely deployment of sensors and the early retirement of high‐voltage circuit
breakers, life‐cycle data is missing, leading to an inability to accurately predict the …

This paper proposes a design of a fault diagnosis algorithm for circuit breaker springs based
on fuzzy clustering. The features of the fault state signal are extracted by combining the …

This paper mainly analyzes and monitors four monitoring variables, such as circuit breaker
opening and closing coil current, moving contact stroke, partial discharge and contact …

With an increasing share of distributed generation, vacuum interrupters see more switching
operations, which makes them more susceptible to contact wear and reduced life …

The design of bypass switches is essential to protect the auxiliary converter connected to the
HV/MV power transformer. In this paper critical fault cases are used to determine …

Rural distribution lines are widely distributed and dispersed, involving numerous circuit
breaker equipment. Detecting mechanical faults on each circuit breaker requires significant …

This run-to-failure vacuum circuit breaker dataset mechanical test dataset was collected at
the High Voltage Laboratory of ETH Zurich, Switzerland. It contains run-to-failure data …

The transition from a centralized power grid towards a more decentralized power grid with
renewable energy generation leads to challenges regarding voltage and power quality …
