Device Settings Report

ETAP Star Device Coordination Setting Reports Manager provides comprehensive and customizable device setting reports including sorting and filtering options such as device settings report based on substation / bus IDs.

The manager allows you to preview and print the protective device setting data, using the Crystal Reports® format or Microsoft Excel® format. Tabular protective device setting report can be generated and customized.

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 TCC Curve.

ETAP Star - Making a User Curve - Part 1

There are cases when a user needs to draw specific curves onto a Star TCC presentation which is not included in the ETAP Star standard library. Applying ETAP "User Curve" is the solution for that.
