Szukana fraza: [Abstrakt = "The paper describes a vector analysis method of transformer tank vibration. The suggested diagnostic method is based on the sound intensity measurement near the tank volume. The vibroacoustic examination of mechanical condition of active part \(winding and core\) is performed mainly with an accelerometric sensor fastened to the tank surface. Such diagnostic examination allows a local \(spot\-wise\) evaluation of vibration acceleration and can lead to erroneous conclusions. The suggested method, on the other hand, allows an image to be obtained – a vibration map of the entire tank surface of the examined transformer."]
