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 interpreta

Aging of power transformers is one of the biggest challenges electrical utilities face. As transformers are commissioned, their insulation system composed of liquid (oil) and solid (paper and pressboard) insulations will deteriorate over time, jeopar

Condition monitoring data in the form of oil test results are important for transformer ageing assessment and asset management. In this paper, Analysis of Variance (ANOVA) based factorial analysis was demonstrated as a data mining technique for ident

Interpretation of oil test data for transformer insulation condition is essential towards justifying asset management practices. Traditionally, an empirical formula is used by asset managers. This work introduces principal component analysis (PCA) an
