| Abstract: | The 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. |
