Consideration of reference impedances and public supply network impedances for use in determining disturbance characteristics of electrical equipment having a rated current ≤ 75 A per phase Ingestion-build-159183 verifiable1 Scope 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 incorporated in IEC 60555 and which are now incorporated in some parts of IEC 610003. In addition, information is given on the impedances of public supply networks associated with service current capacities 100 A per phase.
