- Scope
- This document gives information on the available information and on the factors to be considered when deriving reference impedances, which were included in IEC 60555 and are now included in some parts of the IEC 61000 3 series. In addition, this document also gives information on the impedance of the public power supply network with a supply current capability greater than or equal to 100A per phase. This document is suitable for obtaining information on the consideration of the reference impedance and the impedance of the public supply network for determining the disturbance characteristics of electrical equipment (rated current per phase less than or equal to 75A).
