Solkor protection
WebLine differential protection. The Reyrolle 7SR18 Solkor line differential protection device is specifically designed to provide differential protection and control for overhead lines and cable feeders. Subscribe to our newsletter. WebLet us consider the following 20 kV power system in figure 4 (taken from [1] and modified). In normal operation, the distance protection device ‘D’ at point A sees an impedance equal to the sum of the impedance of power lines Z V1, Z V2, and the load impedance, Z Load.Since Z Load >> Z V1 and Z V2, the impedance measured by the distance protection will be very …
