Purpose. Application of analytical analysis on the available methods of monitoring the power transformer in order to classify and systematize the available information to identify rational, from the standpoint of operated electrical measuring equipment for transformer substations.
Methodology. The use of methods of analytical classification and systematization of existing monitoring methods in the field of practical research and obtained field results.
Findings. Power transformers remain the heart of the power grid and Smart Grid network of any level of the hierarchy of structure and architecture. As a rule, the transformer as an estimated element of the network is put into operation once and kept in working loads, alternating monitoring and scheduled restoration work, until the complete loss of working condition required for the operation requirements. Therefore, most transformers are in operation over the regulated period of more than 20 years.Carrying out the need for flexible analytical assessment and classification of existing methods of monitoring the power transformer, systematization of known information for a wider range of specialists in the energy sector.
Originality. It is established that due to the complexity of modern monitoring methods the time required for their selection and use in accordance with the structure of the transformer decreases with increasing systematization and classification of the relevant methodological material. The presented systematization reduces the cost of time and material resources when choosing the necessary method of the power transformer monitoring.
Practical value. Systematic classification of available monitoring methods in the appropriate relation to the families of methods and zones of monitoring mounting to search for a signal of transformer failures.
