A novel scheme for current-only directional overcurrent relay
International Journal of Electrical Power & Energy Systems, 2016 Abstract Overcurrent relays are widely used as main protection in sub-transmission and distribution systems. In mesh and multi-source networks, application of directional relay is unavoidable. Traditional directional overcurrent relays use the reference voltage phasor as the polarizing quantity to estimate the direction of the fault.
