Abstract

To bring the definition of technical efficiency relay protections high-voltage electrical network, especially for the distance relay protection. To analyze the technical actions to limit and expand the characteristics numerical distance relay protection in order to reduce losses and improve functioning protection. Considering the specifications, efficiency and losses of the backup stages distance relay protection on high-voltage lines. Based on the analysis of technical efficiency proposes recommendations for designing and setting backup stages distance relay protection of high-voltage lines electrical network.
