Journal ArticleDOI
Circuit-Breaker Automated Failure Tracking Based on Coil Current Signature
TL;DR: In this paper, a new algorithm using trip and close coil current (CC) signature is proposed to detect the mode and cause of circuit breakers incipient failures, and the failures and their causes are categorized based on the outcome of these investigations.
Journal ArticleDOI
Data Mining of Online Diagnosed Waveforms for Probabilistic Condition Assessment of SF $_{6}$ Circuit Breakers
TL;DR: To establish a circuit-breaker (CB) online monitoring system, the development of an effective diagnosis framework is essential to accurately assess its condition while under operation, and to foresee any risk of failure before it would be possible to plan for the required maintenance on the CB sufficiently ahead of a failure occurrence.
Journal ArticleDOI
Fault Analysis of High-Voltage Circuit Breakers Based on Coil Current and Contact Travel Waveforms Through Modified SVM Classifier
TL;DR: Coil current and contact travel waveforms are focused on as significant signals that bear helpful information about the fault occurrence for a typical EDF, 72.5 kV, SF6 HVCB.
Journal ArticleDOI
Condition Monitoring of High Voltage Circuit Breakers: Past to Future
TL;DR: This paper has attempted to make a bridge from past to future research trends in the failure diagnosis of HVCBs, and presents challenges dealing with real-time assessment of the diagnostic signals relating to measurements, and analyses.
Journal ArticleDOI
Priority Assessment of Online Monitoring Investment for Power System Circuit Breakers—Part I: Qualitative-Quantitative Approach
TL;DR: In this article, a method to find the most critical breakers for enforcing effectively the CBs CBM planning in a power system is proposed, which is applied on a sample transmission substation with a breaker-and-a-half configuration.
