Abstract

The authors describe tests on the relays on a long 500 kV AC line carried out on site using the real-time digital simulator developed by the Manitoba HVDC Research Centre. The purpose of the tests was to examine the relay behavior when series compensation is inserted in the line in 1993. New settings for the relays have been found which will give adequate cover for all faults although some faults will be entirely dependent on the communication link for short clearance times.
