Abstract

The paper presents the etalon method for calculation of asymmetrical short circuit current distributions in ground wires on overhead power transmission lines. Proposed approach is based on presenting a line as multi-wire system, and allows taking into account factors that other methods based on the nmethod of symmetrical components ignore. This etalon model allows to determine the values of the currents on each wire, as well as to assess the applicability of using for this purpose, assumptions in simplified methods. The exact calculation algorithm is presented, the case in point example is showed as well.
