Designing copper wiring out of high voltage substations: A practical solution and actual installation

The technology of protection and control systems has been continuously evolving, integrating increasing numbers of functions over the last several decades, and delivering significant improvements in dependability, security, sensitivity, accuracy and greater reduction in equipment footprint. The paper presents a robust P&C system based on IEC 61850-9-2 process bus for distributed protection, metering and control and reports on a pilot installation for a 345 kV transmission line application.
