Understanding degradation and failure - what causes failures in high-voltage electrical assets and how can they be prevented?

摘要

Forensic science is best known for identifying the causes of aircraft crashes, or gathering criminal evidence, but it is increasingly applied to the understanding of degradation and failure mechanisms which lead to electrical equipment failure and cause network outages. Lessons learnt through forensic investigations can reduce the occurrence or repetition of expensive and dangerous failures, and ultimately lead to an increase in the safety and reliability of power system assets. A forensic investigation may also provide key legal evidence, leading to prosecution under health and safety laws and charges of corporate manslaughter, as well as apportioning responsibility for the financial consequences.
