A method of handling a reclosing operation of a recloser in a power system subject to a fault. The method includes a) determining a fault current for each electrical phase, the fault current being determined by a difference between measured current values and a sinusoidal model of a current prior to the fault, bI) calculating a respective sinusoidal model of the fault current for each electrical phase using samples taken before the fault, bII) selecting two sinusoidal models with the largest amplitude to represent faulted electrical phases, bIII) calculating a plurality of sub-features based on the two models, and bIV) determining a main feature value based on the plurality of sub-features, bV) determining, based on the main feature value, whether a temporary fault is present, and c) providing control instructions that the recloser is to reclose in the event that the fault is a temporary fault.
