Dynamic Stability Focus

Dynamic stability simulations are performed in the Dynamic Stability focus. To enter this focus, on the Home tab, click Dynamic Stability. You need to have a completed one-line to enter an analysis focus. When you enter the Dynamic Stability focus, EasyPower window changes as shown in the figure below.

Note: If you have purchased only the Transient Motor Starting module and not the Dynamic Stability module, your menus and options will reflect the names "Transient Motor Starting" or "TMS" instead of Dynamic Stability.
