A directional overcurrent relay using a superconducting fault current limiter voltage as a relay element includes: a current measuring circuit measuring a current of a line connected from a system power source to a load, a voltage measuring circuit measuring a voltage at both ends of a ...
Overcurrent relays are widely used for protection of power systems, directional ones for transmission side, and nondirectional ones for distribution side. The fault direction may be forward (between relay and grid), or reverse (between relay and source), the normal power flow being from source ...
