Abstract: To heighten sensitivity of permanent fault identification for
single-phase-to-ground fault, a three-phase adaptive reclosure in transmission lines with shunt
reactors is developed. It is found that the shunt reactor zero modal current gets with different
free oscillation frequencies in transient fault or permanent fault fin the case of
single-phase-to-ground. An identification model of shunt reactor zero-modal current is
established, which includes decaying DC component and two frequency components
corresponding to transient fault and permanent fault. Once the single-phase-to-ground fault
occurs and circuit breakers open, each frequency component is obtained by least square fitting,
where shunt reactor zero-modal current is available. The amplitudes of various frequency
components are adopted to distinguish the permanent faults from transient faults. EMTP
