    Calculation of specific operating modes of relay protection for AC traction networks by K. S. Subkhanverdiev

    Published 2020-09-01
    “…Relay protection of traction networks against short-circuit currents in alternating current sections should have both selectivity and speed. However, in areas with an increased probability of burnout of contact wires during a short circuit, selectivity is often put away to increase the speed of response. …”
