Abstract :
This paper contains summary information on Diacs technology principles comprising the following subjects: power transformers on-line testing and defects location procedure; on-line diagnostic technology and data analysis; examples of test results. Possible failure scenarios are observed here, as well as general tools available for power transformer life assessment. Specific technology of Diagnostic Methods Synergy for transformer insulation analysis is described in the paper, one the most important components of which are methods of Double-Coordinate Location and n(Q) distribution analysis, on-line PD location, gas-in-oil analysis, thermovision.
