What is the cause of oil leakage in oil immersed transformers? Next, the editor will give you a brief introduction.1. Welding qualityThe shell of an oil immersed transformer is a combination of welded and connected steel plates. Due to the long weld seam and numerous welded joints, high requirements are…

The fault diagnosis method for oil immersed transformers is to analyze the collected transformer fault information and determine the type of transformer fault based on the data analysis results. During this process, the accuracy of the collected information plays a crucial role in the accuracy of fault diagnosis. There are…

The degradation of transformer insulation is often the result of a combination of multiple factors, not a single factor. Partial discharge is not only the cause of insulation degradation, but also a precursor and manifestation of insulation degradation. The direct causes of partial discharge in transformers usually include:① There are…
