The SDIPF reliability curve of old EHV power transformers

Vitaly Gurin

Sažetak

The further development of UHV and UHV transmission lines and the aging of large power transformers (half of which are over 30 years old) keep the developers of specifications of new transformers working for many years to come. To help them, a historical overview of the failures of EHV transformers in the 20th century was made in terms of modern Asset Lifecycle theory embedded in the SDIPF curve (Specify - Design – Installation - Potential failure – Failure). The main causes of accidents were shortcomings in Specify and Design.
