The detection of winding short circuits in single-phase double-winding transformers / Bohdan Dmytryk, Oleksandr Ravlyk // Litteris et Artibus : proceedings of the 5th International youth science forum, November 26–28, 2015, Lviv, Ukraine / Lviv Polytechnic National University. – Lviv : Lviv Polytechnic Publishing House, 2015. – P. 148–151. – Bibliography: 1 title.https://ena.lpnu.ua/handle/ntb/39574The object of this research is to offer a new method of identification of winding short circuits in power transformers of all classes. This method presents fast acting and absolute selectivity during different emergency modes. It’s based on the analysis of digital values of current and voltage in transformer’s windings with further calculations of active resistance.enwinding short circuitdouble-winding transformerprimary windingsecondary windingsimulation modelcoreexternal short circuitno-load modeloadConference Abstract148-151
