IEC TR 60725:2005 ED2

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 IEC TR 60725:2005 ED2

Publication date:   May 30, 2005

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 formerly incorporated in IEC 60555, 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.
