Doble Boosts Transformer Testing Productivity, Accuracy and Performance with New M5500 Sweep Frequency Response AnalyzerNovember 2, 2020
Next-generation SFRA instrument dramatically reduces testing time and maintenance costs while ensuring high-quality measurements in the field.
Sweep frequency response analysis (SFRA) is a popular test to confirm the mechanical and electrical integrity of a transformer. However, the resulting traces can be difficult for field personnel to interpret due to the visual nature of the data. It is more straightforward to compare numbers against prior data or against a stated limit than to interpret subtle differences in SFRA traces. If setup-related issues are not addressed during the testing process, return trips are often required to take additional shots to represent the transformer more accurately. These trips cost time and resources, so being able to identify a setup problem early can keep extra work to a minimum. A trained eye can focus in on a problem area quickly and identify a test setup issue promptly. Such confidence only comes at the expense of hours spent analyzing data. This article discusses common setup problems and their impacts.
Health index (HI) approach has been adopted widely as a tool that assists the asset managers to prioritise their plans and actions. However, the conventional computation of HI, which is based on scoring and ranking, has several drawbacks. In this work, the fuzzy logic approach is utilised to build up an intelligent HI system to assess the condition of power transformers based on oil quality and DGA results.
The episode covers the importance of upscaling infrastructure and maintenance with the transition of renewables against the background of climate-driven weather events, the expansion of microgrids, and how Doble, specifically can support utilities through the transition.
