Omfang: IEC 60909-0:2016 is applicable to the calculation of short-circuit currents in low-voltage three-phase AC systems, and in high-voltage three-phase AC systems, operating at a nominal frequency of 50 Hz or 60 Hz. It establishes a general, practicable and concise procedure leading to results which are generally of acceptable accuracy and deals with the calculation of short-circuit currents in the case of balanced or unbalanced short circuits. This second edition cancels and replaces the first edition published in 2001. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:<br /> - contribution of windpower station units to the short-circuit current;<br /> - contribution of power station units with ful size converters to the short-circuit current;<br /> - new document structure.<br /> <br /> This publication is to be read in conjunction with <a href="https://webstore.iec.ch/publication/3888">IEC TR 60909-1:2002</a>, <a href="https://webstore.iec.ch/publication/3889">IEC TR 60909-2:2008</a>, <a href="https://webstore.iec.ch/publication/22267">IEC 60909-3:2009</a> and <a href="https://webstore.iec.ch/publication/3892">IEC TR 60909-4:2000</a>.
