Abstract: | A set of measures that can be implemented by the Relay-Protection and Automated-Equipment Service for Centralized Dispatch
Regulation (CDR) in Siberia to determine the location of damage sustained by inter-system 550-and 220-kV transmission lines
maintained by the United Power System (UPS) of Siberia, and the methodology and technology of damage-location determination
(DLD) are described. The damage sustained by the 500-kV high-voltage lines (HL), and the accuracy of DLD relative to zero-sequence
emergency parameters are analyzed statically.
