In this final work of the bachelor, a description and comparison of various methods for assessing the technical characteristics of current transformers is presented and experiments were carried out to determine the reliability of insulating structures. An analysis of several methods of diagnosing was also carried out, an integral indicator of the technical condition was calculated. For a visual presentation of a comprehensive assessment of the technical condition of the current transformer, an experiment was carried out to detect defects in a porcelain insulating structure using an ultrasonic method using a special device - a flaw detector. It is concluded that the management of the technical condition and the conduct of research must be carried out directly in a complex manner, since each stage of the life cycle of elements of high-voltage installations has its own methods of implementation, which is why the efficiency and durability of operation depends on the totality of the measures taken. |
