Abstract :
It is always desirable to transmit as much power as possible over major transmission line interconnections, and the 500 kV line linking Manitoba in Canada to Minnesota in the USA is a good example. Here, the authors describe how delta-current admittance relays detect severe power system disturbances and initiate a power reduction signal on this HVDC transmission system
