Abstract

Technical solutions aimed at improving the reliability of power supply to consumers of the 6-10 kV network are proposed, a block diagram of a fundamentally new device for diagnosing and protecting cells of 6-10 kV power cable lines with a single algorithm of operation is shown, which allows simultaneously performing current protection of the controlled feeder and monitoring with a predictive assessment (residual resource) of the state of the cable insulation material. A possible scheme of interaction of elements of an active-adaptive power unit of 6-10 kV is shown on the example of a cell of a 6-10 kV cable line. he device will allow you to control leakage currents in distribution networks, taking into account the remaining cable life, reduce insulation losses during power transmission and increase the energy efficiency of the controlled network by reducing power interruptions to the consumer. The quantitative values of the device will be determined after its introduction into trial operation.
