description: This work is devoted to the study of acoustic defectoscopy, in particular, AR-700 and NL-camera devices, their application features and relevance of use in comparison with other non-destructive testing methods. Tasks that were solved in the course of study: 1. determining the importance of testing electrical equipment and their problems. 2. study of the factors of appearance of partial discharges and the conse-quences leading to initiation of defects. 3. study of principle of operation of acoustic flaw detector AR-700, fea-tures of its application, analysis of data obtained during device application. 4. comparison of various non-destructive testing methods (ultrasonic and ultraviolet cameras, thermal imaging testing) based on their efficiency and eco-nomic component. The work is carried out on the basis of Public Joint-Stock Company Ros-seti "Lenenergo", where presented electrical equipment is tested using indicated control devices. Visual analysis of obtained data is carried out, during which defects are found at an early stage of their development. Analysis is carried out using the Inva Portable software, equipped with necessary tools for fine-tuning and filtering measurements. As a result, partial discharge distribution graphs are presented, created on the basis of data analysis obtained using the AR-700 device. When considering these curves, a conclusion is made about nature of partial discharges and defect that originates due to them. Various problems are shown during acoustic flaw detection, such as, for example, difficulties in diagnosing remote and energized electrical equipment by contact method, exclusion of extraneous noise during examination, and expansion of spectrum of perceived sound frequencies. In addition, a comparison of non-destructive testing methods is made, indicating features of certain device application, as well as a general conclusion. Based on the research, it is decided to modify NL-camera to increase measurement efficiency, and thermal imaging method is chosen as the most appropriate method of non-destructive testing.
