This technical report records the information that was available and the factors that were taken into account in arriving at the reference impedances that were formerly incorporated in IEC 60555 1), but which are now incorporated into some sections of IEC 61000-3.
In addition, information is given on the impedances of public supply networks associated with service current capacities ≥100 A per phase.
