Bibliography

Provides 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 61000-3.

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 61000-3.

In addition, information is given on the impedances of public supply networks associated with service current capacities ≥100 A per phase.
