Abstract :
This paper describes a double circuit line protection relay which has all 6 line currents and voltages available for processing. This allows several alterations to the standard 3-phase distance package which enhance the performance of the protection system. Results are presented for the relay fed with simulated waveforms from a Playback Simulator. The system used in the simulations is modelled on a 69 kV parallel line in the Winnipeg Hydro network
