摘要: Overcurrent relays are widely used for power systems protection. Transmission side uses more directional type relays, while distribution systems, e.g., radial and ring-main subtransmission use nondirectional types. The fault direction may be forward (between relay grid), or reverse source), the normal flow being from source to grid. Traditional overcurrent utilize reference voltage phasor estimating of fault. This requires measurement both current using respective sensors. makes costly than type. In this paper, a novel current-only detection possibility is highlighted along with theoretical, test signal analysis, challenges associated solutions. Possible utilizations in protection described, which key focus area enabling smart
