Abstract

The article offers protection of unbalance conductivity of the individual phases. The principle of operation, the choice of form zones and settings relay of conductivity for building protection against unbalance networks 110–220 kV are substantiated in the paper. The validity of assumptions is verified according to experimental data. The features of the application of the protection of conductivity in the networks of various configurations are analyzed. Determination of sensitiveness and verification of selectivity of protection on conductivity are executed.
