The operation mode of single-stage current transformer with open secondary circuit / Roman Ferensovych // Litteris et Artibus : proceedings of the 6th International youth science forum, November 24–26, 2016, Lviv, Ukraine / Lviv Polytechnic National University. – Lviv : Lviv Polytechnic Publishing House, 2016. – P. 175–176. – Bibliography: 7 titles.https://ena.lpnu.ua/handle/ntb/40736The operation mode of current transformer with open secondary circuit is emergency and is accompanied by the appearance on the terminals of its secondary winding overvoltages, which are dangerous for secondary equipment and attending personnel. In the paper analysis of operation mode of single-stage current transformer type TV-35 (ТВ-35) after disconnection of its secondary circuit is carried out. The influence of active losses in magnetic core of current transformer TV-35 (ТВ-35) on the values of its secondary overvoltages is investigated.encurrent transformersecondary circuitdisconnectionterminals of secondary windinghigh-voltage pulsesovervoltagesmagnetic coreactive lossesConference Abstract175-176
