The paper presents the impact of the digital communication channels parameters on the line differential protection operation reliability. According with local power system utility statistical data, the numerical differential line protection operation reliability and effectiveness is highly dependable of the communication channel parameters stability and data exchange security. The time delays parameters of the communication channels were tested and analyzed by means of the specially developed device “Line Tester”.

Keywords
