IEC TR 60909-1:2002 pdf free download.Short-circuit currents in three-phasea.c.systems - Part 1: Factors for the calculation of

short-circuitcurrents according to lEC 60909-0.

• neglecting loads and capacitances by calculating according to IEC 60909.0 (see 2.3.1);

• the subtransient behaviour of generators, power•stalion units and molors.

The meaning of the voltage factor e is Illustrated for a simple model of a radial network in 2.14 Furthermore, results of extended calculations given in 2.2.5 and 2,3.4 demonstrate the possible deviations of calculations with the equivalent voltage source at

the short-circuit location against the worst-case values found with a special procedure using the superposition method.
