In this example, the short circuit current for Node Three will be computed according to the IEC 60909 standard. To do this, first select only Node Three. Secondly, from the main menu choose Calculate | Basic | IEC 60909.
Hereafter, the IEC 60909 calculation settings form shows up.
In this example we choose a symmetrical short circuit calculation. After closing this form by pressing the OK button, the calculation will be performed. The illustration below shows the result.
The symmetrical short circuit current on Node Three should be 22,50 kA. Detailed information can be examined by clicking on Node Three with the right mouse button.
This “Getting Started” is only a very short introduction to Vision, but from this point on the user should be ready to discover all of Vision’s functionalities on its own.
