Abstract

This paper deals with electromagnetic processes occurring in case of LG fault for parallel lines of different voltage levels (from 6 to 35 kV) and their relay protection operation. The most probable cause of false tripping of relay protection devices in parallel less nominal voltage line in case of LG fault in a higher nominal voltage line is considered. Created and patented device for allowing eliminating the false tripping of relay protection is described. The paper contains detailed vector diagrams that may be useful not only for engineers and researchers in the field of relay protection, but for everyone who are interested in evaluating the interference level or in selecting and applying any devices protection measures.
