A A digital algorithm for the protection of parallel transmission lines has been implemented on a 16-bit single board computer. It has been tested on a physical model consisting of two synchronous machines connected through a double circuit line. The algorithm is based on comparing magnitudes of currents of two parallel lines. Details of the experimental set-up and the results of on-line tests for various operating conditions are presented. A procedure to adjust the relay settings adaptively is also incorporated. The results illustrate the successful operation of the algorithm in detecting faults on parallel lines.
