Specific Reliability Indicators of 0.4 kV Electrical Networks

Thestatistical data on emergency and planned outages of 0.4 kV electrical networks in one of the Central regions of Russia in the period 2018–2023 are analyzed. As a result of the analysis, the values of specific reliability indicators and trends in their change over 6 years were identified. It was revealed that the values of the failure flow parameter do not exceed the reference values up to and including 2022, and in 2023 they exceed them by 1.2 times. The values of specific disconnected capacity per outage in 2023 decreased by 17.5 times compared to 2018, the average value per outage is 0.0009 MW.
