IEC EN 60909-2 Short Circuit Currents in Three Phase Alternating Current Systems - Part 2: Electrical Equipment Data for Short Circuit Current Calculations

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60909-2 testing. IEC EN 60909-2 contains electrical equipment data collected from different countries to be used when necessary for the calculation of short-circuit currents according to IEC EN 60909-0. Applicable for calculating short-circuit currents in low-voltage networks, if they are suitable for typical equipment used in the user's country. In general, electrical equipment data is given by the manufacturers on the nameplate or by the electricity supplier.

The data collected and their evaluation can be used for medium or high voltage planning purposes and also for comparison with data given by manufacturers or electricity suppliers. Electrical data for overhead lines and cables can also be calculated from physical dimensions and material in some cases according to the equations given in this report.

The presented data are necessary for the calculation of short-circuit currents. Sometimes they are presented in the form of curved sheets, sometimes in the form of examples in tables. As far as easy equations are concerned, it is given for calculating positive sequence and zero sequence short-circuit impedances for overhead lines and cables. In some cases, average values ​​or characteristic trends are given as a function of rated power, rated voltage, etc.

EUROLAB assists manufacturers with IEC EN 60909-2 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
