High acetylene in transformer oil
WebAcetylene is seen as a symbol gas to distinguish arcing/sparking occurrence and overheat inside the power transformer. However, conventional detectors suffer from gas consumption, unrepeatable measurement and regular calibration. Based on Lambert Beer's law, this paper put forward near-infrared absorption spectrum method to detect … WebA high rate of acid formation means that the oil is thermally stressed, which causes the oil to degrade at a faster rate. This can be an indication of inadequate cooling due to poor …
