Typical big industrial substation is supplied by two HV 110 kV lines. Additionally busbars are connected to generators, synchronous motors and induction motors. During short-circuits on busbars currents are flowing from many sources. The short-circuit currents may be higher than short-circuits strength of busbars. In this case operation of coupling of busbar section is very important. This paper contains analysis of functioning of busbar section coupling in industrial substations.
