Calculation of short-circuit currents The initial short circuit currents Ik" can be calculated either using the superposition method, or according to the IEC 60909 standard ( IEC with some minor limitations. The latest publications can be downloaded from the Schneider Electric internet web site. Code. currents as laid down by standards such as IEC 60909.
Short-circuit analysis of the onsite electric power system at Ringhals. Put the example files *(single line diagram files) in a directory of your choice. The IEC 60909-0 standard is used in order to calculate various types of short-. Keywords short-circuit current, electric power system, IEC 60909-0, initial short-.
Short-Circuit ANSI & IEC - ETAP In addition, the activation of protection relays is displayed. ) - Initial short circuit current with the superposition method, or according to IEC 60909 - Calculates currents as a function of time (not in IEC-calc.) - Shows the activation of overcurrent protection relays and distance relays (not in IEC-calc.) - different protection relays available: definite time, inverse time, combined phase,ground, sequence (PGQ), electromechanical, user defined, distance l - Several tens of overcurrent relay curves programmed in (IEC, ANSI, (ABB, Westinghouse, English Electric, etc) - Phasor display of currents and voltages - Contains a simple relay coordination graphics page - When using the superposition method, the prefault state can be taken from a load flow calculation - Can produce the input file (*file) for the Microtran (EP) transient simulation program (tested only with the student version) - Can produce the input file (*file) for the ATP transient simulation program - Handles both radial and meshed networks May be slow in the case of "large" networks ( "large" = clearly bger than the screen!
