What is Transformer Failure Analysis 2003 about?

This document summarizes analysis of 94 transformer failure cases from 1997-2001. The largest number of failures occurred in utility substations, while the highest costs were from generator step-up transformers. The leading cause of failures was insulation failure, followed by design/manufacturing errors. On average, failures cost $8,990 per MVA. The aging worldwide transformer fleet and increased loads are contributing factors to the risks of failures.
