Analysis and classification of failures of capacitor banks at 110 kV substations of "Bashkirenergo" Ltd

Abstract

In world practice, there is no unequivocal explanation and visual representation according to the life and reliability of the battery from static switching transients BSC-110, the type of the circuit breaker in BSC-110 and parameters of regime and network. This paper describes the experience of operating in the BSC-110 in Ltd "Bashkirenergo" and presents the calculation of reliability and probability of failure-free operation of capacitors BSC-110. It describes the effect of re-strike or re-ignition, and surges during switching BSC-110 on the life of capacitors. © 2014 WIT Press.
