Condition Monitoring of Power Transformers
One major issue with the SFRA measurements is their repeatability on-site in the range of high frequencies when it comes to periodic condition monitoring of transformer windings. SFRA measurements can be affected by a number of factors such as layout and grounding resistance of the ground extensions of SFRA cables which may lead to misinterpretation of the test results.
