Assessing the reliability of electric power systems is a very difficult and non-trivial task. Currently, there are various approaches and methods for quantifying reliability, which are mostly based on statistical data on failures of elements of electrical energy systems. The article provides statistical data on failures and their causes in the main and distribution electric networks, as well as on their condition.
Currently, the issue of increasing the reliability of electric power systems is acute due to the high level of wear of electrical equipment. To solve this problem, an adequate assessment of the reliability level of existing electrical systems is necessary. The assessment of the reliability of electrical grid equipment is based on a large amount of statistical data on the number and causes of failures. The article provides some statistical data on malfunctions and their causes for power and measuring transformers.
