Star Plot Options


ETAP Star Protective Device Coordination software provides a Plot Options tool with all the necessary options to customize the display of the Time Current Characteristic Curve. Using Plot Options, it is possible to customize the display of the current and time axes, legend, grid, curve plotting colors and properties, and more. By setting default Plot Options a custom layout can be created without having to repeat the process for each Time Current Characteristic Curve.


Graphical Adjustment


Overcurrent Protective Device operating curves can be graphically adjusted in the Star View without requiring the respective property editor to be opened. Drag and drop handles are provided on the protective device characteristic curves to identify adjustable regions. Available ranges for a selected protection device curve can be displayed and identified by clicking the Hide/ Show Range button. The available ranges are grayed out when an adjustable overcurrent device curve is selected.

Multiple Motor Starting & Damage Curves


Motor starting curves based on rated values can be plotted in ETAP Star for the purpose of determining overload settings for motor protection devices. The effect of varying the constant terminal voltage can be analyzed by adjusting the voltage values at the motor terminal.

Starting curves obtained through Motor Starting Analysis Software can also be plotted in ETAP Star to give a more accurate presentation of the motor starting curve.

Stator and rotor damage curves can also be plotted giving a comprehensive view of the motor behavior and thermal limits. Stator curves can be plotted based on multiples of machine full-load amps or actual amp values.

Intelligent Alert View


With ETAP protective device coordination software you can troubleshoot your device coordination and protection studies for any Star View Time Current Characteristic Curve. The Alert View button on the Star View provides a summary of alerts or messages (low priority alerts) that provides hints as to how and why a particular device curve is not being displayed or missing information regarding a device.
