description: In this graduate work of the bachelor, a comprehensive survey of an oil-filled measuring current transformer of the type TFZM-110 kV was carried out and an assessment of the resource of the apparatus. The main goal of the work was to show that timely and classified identification of any deficiencies and aging of the insulation service can prolong the life of the apparatus. An analysis of the characteristics of the current transformer was carried out, and a diagnostic system for assessing the reliability of insulation was carried out. The analysis of the characteristics of the insulation of the transformer at various stages of its operation, from development to the full stage of maintenance of one or another part of the insulation, is carried out. A methodology for assessing the measuring current transformer at various stages of the design and operation of the apparatus was worked out. The effectiveness of the use of three-stage control when measuring insulation was substantiated. In ensuring the maintenance of the life cycle of the measuring current transformer, conclusions on the need for the implementation of preventive work plans. For the visual application of the assessment of the resource and quality of insulation, an experiment was set up describing the actions of ultrasonic, thermal imaging and vibration devices.
