For a synchronous generator use Rm see 3. I certification technical documentation ci ci The resistance is to be idc if the peak short-circuit current ip or the d. If the short circuit is a far-from-motor short circuit i. The type of short circuit which leads to the highest short-circuit current depends on the values of the positive-sequence, negative-sequence, and zero-sequence short-circuit impedances of the system.

Android studio 2.2.3 for mac. However, parties to agreements based on this part of IEC are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. Factors for the calculation of short-circuit currents in three-phase a.

The calculation of low-voltage breaking currents after a time deiay tmingreater than 0,1 s is not included in this standard; generator manufacturers may be able to provide information. For large transformers the resistance is so small that the impedance may be assumed to consist only of reactance when calculating short-circuit currents. Figure 3 – Characterization of short circuits and their currents Figure 4 shows an example of the equivalent voltage source at the short-circuit location F as the only active voltage of the system fed by a transformer without or with on-load tap-changer.

In this case special considerations beyond the scope and procedure given in this standard have to be taken into account see for instance 2. The values of positive-sequence and negative-sequence impedances can differ from each other only 600909-0 the case of rotating machines. The impedance ZrS1in equation 38 or 43 is used to determine the lec short-circuit current ILT in figure 13 for the short circuit in F3.

For increased accuracy, equations 79, 76and 77 can be used.

For higher temperatures than 20 OC, see equation 3. If Si is used in spite of this in connection with short-circuit calculations, for instance to 69009-0 the internal impedance of a network feeder at the connection point Q, then the definition given should be used in the following form: The capacitances of lines overhead lines and cables of low-voltage networks may be neglected in the positive- negative- and zero-sequence system.

Calculation of short-circuit currents of 6099-0 motors in the case of a short circuit at the terminals see 4. Request permission to reuse content from this site. When calculating short-circuit currents in systems with different voltage levels, it 6909-0 necessary to transfer impedance values from one voltage level to another, usually to that voltage level at which the short-circuit current is to be calculated.

At this date, the publication will be 0 reconfirmed; 0 withdrawn; 0 replaced by a revised edition, or 0 amended. Factor p for calculation of short-circuit breaking current 1, When calculating the partial short-circuit current Iwc Factors f o r the calculation of short-circuit currents in three-phase a.

Low-voltage motors are to be taken into account in auxiliaries of power stations and in industrial and similar installations, for example in networks of chemical and steel industries and pump- stations. This can lead to 609909-0 situation where the partial short-circuit currents are too small to operate any further protection device, particularly in the case of minimum short-circuit currents.

This is the only active voltage of the network 1. E” Subtransient voltage of a synchronous machine f Frequency 50 Hz or 60 Hz Ib Symmetrical short-circuit breaking current r. The total 6090-0 in F1 or F2 figure 13 is found by adding the partial short-circuit current ILrnv, caused by the medium- and low-voltage auxiliary motors of the power station unit. The following values 60990-0 the fictitious resistances RGfmay be used for the calculation of the peak short- circuit current with sufficient accuracy.

All other active voltages in the system are assumed to be zero. NOTE For some near-to-generator short circuits the value of id. It is assumed that the operating voltage at the terminals of the generator is equal to UrG. This correction factor irc not be introduced for unit transformers of power station units see 3.

The effect of series capacitors can be neglected in the calculation of short-circuit currents, if they are equipped with voltage-limiting devices in parallel, acting if a short circuit occurs. Short-circuit currents and short-circuit impedances may also be determined by system tests, by measurement on a network analyzer, or with a digital computer.

Examples f o r the calculation of jec currents’ IEC The resistive component uRrcan be calculated from the total losses PkiTin the windings at the rated current IrT, both referred to the same transformer side see equation 8.

The calculation of the 06909-0 peak short-circuit current i, applies to the line conductor and to the instant at which the greatest possible short-circuit current exists. Radial Network Skip to main content. The factor p may also be obtained from figure He has more than 18 years of professional experience kec planning and design of electrical power systems. This does not exclude the use of special methods, for example the superposition method, adjusted to particular circumstances, if they give at least the same precision.

Zero-sequence 6090-90 arrangements for the calculation of unbalanced short-circuit currents are given in IEC CE1- Instead of: In special cases the zero-sequence equivalent short-circuit impedance of network feeders may need to be considered, depending on the winding configuration and the starpoint earthing of the transformer.

This fault is beyond the scope of, and is therefore not dealt with in, this standard. The zero-sequence system impedance Z, of the ieec shall be given by the manufacturer, if needed see 4.
