Ageing of large transformer fleets is a challenge for utilities. To assess the condition of existing transformer fleets, transformer oil is commonly tested for multiple parameters and the data are recorded in large databases for subsequent interpretation. Through analysing multiple databases including oil test results and individual transformer details pertaining to UK in-service transformers operating...
The high level of reliability experienced by power transformers has led to the situation that a large number of aged units are still operating in the power systems. However, uncertainty on how transformers behave when aged causes concerns over the existence of possible hidden failure modes, which have yet to be revealed by failure data. In order to establish whether aged transformers are able to maintain...
Power transformers are considered to be one of the most critical components of a power system. Due to ageing the majority of transformer populations are at or approaching their anticipated design lives, causing growing concerns over possible consequential impacts to system reliability. It is essential for utilities to maintain high levels of system reliability and ensure the continued cost-effectiveness...
