Partial Discharge, Breakdown, Aging and Life Assessment in Electric Power Assets

Expansive reference on power equipment failures, exploring fault detection systems and breakdown mechanisms that lead to failures

Reviewing topics ranging from basic to advanced, Partial Discharge, Breakdown, Aging, and Life Assessment in Electric Power Assets familiarizes readers with failures and their indicators in different pieces of power equipment, different fault detection systems that utilize common indicators, and the breakdown mechanisms leading to failures, covering the entire timeline of insulation degradation from pre-failure symptoms to post-failure assessment. The book includes tables, illustrations, and models throughout to aid reader comprehension along with case studies and tutorials that help put theory into practice.

The book explores the theoretical background behind dielectric materials, the degradation and failures observed in electrical equipment insulation, PD measurement systems that capitalize on the multi-physics nature of PDs, as well as insulation diagnostics techniques, artificial intelligence for condition monitoring, and current power equipment monitoring schemes. Later chapters discuss numerical modelling of the degradation mechanism instigated by PD activity and development of ultra-high frequency sensors used in PD detection.

Additional topics discussed in the book include:

• Challenges associated with health index identification, aging classification, remaining lifetime estimation, and the assessment of industry assets' reliability
• Emission of ultra-high frequency radiation as a result of partial discharge activity
• Machine learning techniques, their role in power equipment assessment, and challenges they introduce in the transition towards smart grids
• Utilization of external and internal sensors for PD detection in gas-insulated switchgear
• Impact of insulating barriers inside gas-insulated switchgear on the attenuation of electromagnetic waves

Comprehensive in scope, Partial Discharge, Breakdown, Aging, and Life Assessment in Electric Power Assets is an excellent reference on the subject for senior undergraduate and graduate students, electric power system engineers, researchers, government planners, policymakers, and stakeholders.
