It is approved by IEC Members and changes the technical normative elements of a particular international standard. An international standard is a document that has been developed through the consensus of experts from many countries and is approved and published by a globally recognized body.

The IEC (International Electrotechnical Commission) is the world’s leading organization that prepares and publishes International Standards for all electrical, electronic and related technologies. Close to 20 000 experts from industry, commerce, government, test and research labs, academia and consumer groups participate in IEC ...

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.

IEC standards cover a vast range of technologies from power generation, transmission and distribution to home appliances and office equipment, semiconductors, fibre optics, batteries, solar energy, nanotechnology, and marine energy, as well as many others.

Clause 9 gives the circuit diagram and the data of a test network and the results for a calculation carried out in accordance with IEC 60909-0, to offer the possibility for a comparison between the results found with a digital program for the calculation of short-circuit currents and the given results for and in a high-voltage network with ...

International Standard IEC 60909-0 has been prepared by IEC technical committee 73: Short-circuit currents. This first edition cancels and replaces IEC 60909 published in 1988 and constitutes a technical revision. Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

国际电工委员会（iec）于1988 年制定了短路电流计算标准，在世界范围内被广泛认可。 此标准由我国国家技术监督局于1995 年4月 6 日批准，1996 年1 月1 日正式成为三相交流系统短路电流计算的国家标准。

Short-circuit current calculation in three-phase AC systems. Abstract: A calculation of the prospective fault current must usually be made when planning or modifying an electrical system. Such calculations may also be required for operational purposes.
