Java-based Three phase (balanced) Short-Circuit Calculation Tool:


The tool has 2 methods for calculating 3-phases short-circuits:

- IEC909 Method: According to standard IEC 60909-0. (max-min)

- Complete Method: Levels under specific loading conditions.




MAIN WINDOW:
To start the calculation of short circuit must access the configuration window. 
This is accessed by any of the following:

1. Menu: Analisys Tools / Static Tools / Technical Tools / Short Circuit Study

2. By clicking the button Short-Circuit of studies toolbar.




GENERAL TAB:
The main window contains two panes, tabs hereinafter called General and advanced.

Method: Choose the method of three-phase short-circuit calculation

Options: IEC909 and Complete
Selected Control Area.

Option one: All Control Areas

Selected Sample bars BusBar: recognized for the system under study. The candidate will be for purposes of calculating the bar failed

SelectedBusbar Button: Search the schematic the active bar and select it as the bar failed

Output File: Prints results as a file using the built-in DeepEditor Zfileviewer 1.01

Complete report: Include in the output file information or subtransient transient currents and short-circuit current peak for each of the branches of the system.

Impedance R: actual value (resistance) of the three-phase fault impedance.
Options: any positive real number. 0.0 pu assumes default.

Impedance X: Value imaginary (reactance) of the three-phase fault impedance.

Options: any real number. 0.0 pu assumes default.

Calculate Button: Starts the calculations with the values selected
Cancel Button: Cancels. Return to schematic



ADVANCED TAB:

Two cells divide this Tab: A fixed and dependent on the method chosen in the "method" of Tab "General". 
The fixed cell labeled "R / X Method" and the variable labels show the advanced options to IEC909 and fill methods.

Cell Fixed: "R / X Method":
Current Peak R / X Method: Shows the two most accurate methods for estimating the peak of the short circuit current.

Options: B and C
Default: C
If the IEC909 option is selected in the choice "method" of Tab "general" variable shows cell advanced options IEC909 method.

Variable Cell "IEC090":
Maximun / minimun: Selects calculate the maximum or minimum effective short-circuit current.

Tolerance: Select calculation accuracy by making an adjustment to the value of the voltage
Options: + / -6 + / -10
