Providing the reliability of adaptive single-phase reclosing (ASPR) in line equipped with any number of shunt reactors (SR), including the case of their absence, are considered and analyzed in this paper. The essence of the proposed work is that in order to provide high reliability of ASPR, is carry out short-term (for 0.1 seconds) one-sided switching on of the emergency phase from the side of the intermediate system, is measuring the current value of the current of this phase at the switched end and comparing it with the specified setpoint. If the current is higher than the specified setpoint, then a short or arc fault is detected in the phase and then it gives a command to disconnecting the line, otherwise it is not a short circuit in the phase and it is successfully will turned on to work on the other side of the line.
Key words: adaptive single-phase reclosing / weak intermediate system / input resistance argument / controlled current in the emergency phase
