Omfang

This part of urn:iec:std:iec:60909-1:2002-07:tr::IEC 60909 is a technical report applicable to short-circuit currents in three-phase a.c. systems. This technical report aims at showing the origin and the application, as far as necessary, of the factors used to meet the demands of technical precision and simplicity when calculating short-circuit currents according to urn:iec:std:iec:60909-0::::IEC 60909‑0.Thus this technical report is an addition to urn:iec:std:iec:60909-0::::IEC 60909‑0. It does not, however, change the basis for the standardized calculation procedure given in urn:iec:std:iec:60909-0::::IEC 60909‑0.References are given in some cases to offer additional help, not to change the procedure laid down in the standard.
