Summary
Group A3.43 was established to advance switchgear condition assessment, building on previous CIGRE publications. Starting with TB 167 in 2000, which outlined circuit breaker monitoring parameters, and culminating in TB 737 in 2018, which focused on non-intrusive condition assessment.
The brochure aims to develop a comprehensive method for assessing switchgear condition, addressing mechanical, dielectric, electrical wear, and auxiliary circuit degradation.
- Chapter 2: Reviews available TBs related to monitoring.
- Chapter 3: Ranks condition indicators and lists degradation mechanisms.
- Chapter 4: Proposes tools for asset assessment, including Sequence of Events and Weighted Correlation Network Analysis, aiming to apply a health index for switchgear to enhance efficiency and reliability.
- Chapter 5: Discusses the integration of monitoring systems into IEC 61850-compliant digital substations, emphasizing interdisciplinary collaboration.
- Chapter 6: Reports the outcomes of interviews with utilities and manufacturers about the applied maintenance approach.
- Chapter 7: Discusses future trends and needs, considering new technologies, evolving competencies, and upcoming environmental regulations.
In summary, the brochure represents a collaborative effort by experts from various fields to enhance switchgear condition assessment, improving reliability and efficiency in T&D switchgear maintenance and operation.
