(UTC-04:00) Eastern Time (US & Canada)
Abstract: High-voltage circuit breakers (HVCBs) are critical components in power systems, and their reliable operation is essential for ensuring the stability and continuity of electricity supply. This presentation will explore the diagnosis and monitoring of HVCBs, drawing upon research conducted by presenter in the past 15 years ago.
The talk will cover various aspects of HVCB diagnostics and monitoring, including:
• Diagnostic Signals: Discussion of various signals used for HVCB condition monitoring, such as electrical signals (e.g., coil current, contact resistance), mechanical signals (e.g., vibration, motion analysis), and gas analysis (for SF6 circuit breakers).
• Intelligent Modeling: Exploration of advanced techniques like artificial intelligence (AI) and machine learning (ML) for analyzing diagnostic signals and predicting potential failures.
• Monitoring Data in Asset Management: How monitoring data can be integrated into asset management strategies to optimize maintenance scheduling, extend the lifespan of HVCBs, and improve overall grid reliability.
• Future Trend: How digital twins foster the prognostics and health management (PHM) in high voltage circuit breakers
The presentation will highlight the importance of continuous monitoring and timely diagnosis of HVCBs to prevent costly failures and ensure the reliable operation of power systems. It will also discuss future trends and challenges in the field of HVCB diagnostics and monitoring.
