The paper presents the idea of a Cross Test Comparison (CTC) method for the analysis of Frequency Response measurement results. FRA is used to detect deformations or electric faults in transformer windings. At the current stage of FRA method development, it is possible to perform repetitive measurements, however there are still problems with interpretation of test results. Authors of this paper found that analysis of results coming from two test setups (end-to-end and interwinding capacitive), which is done simultaneously is a more sensitive tool to detect some faults, and in addition it binds the influence of both voltage sides of a transformer in a single test result. The paper contains results obtained from laboratory tests, where controlled deformations were introduced into windings and also measurements from industry. The CTC method combines both the end-to-end and capacitive interwinding measurements into a single dataset, by subtracting the amplitudes at the corresponding frequencies. The resulting combined dataset is more sensitive in identifying deviations from baseline measurements.
