This paper proposes some extended method for assessment of transient disturbances in HV system with single-phase autoreclosures. Main efforts are addressed to second arc extinction on the basis of recorded voltage in faulty line in presence of arc. Introduced ideas utilizes recent definitions of time-varying power quality indices. A new contribution of the work is a proposition of characteristic based on local values of odd and even harmonics distortion index.
