Device Settings Report

ETAP Star Device Settings Report Manager provides comprehensive and customizable device setting reports in Crystal Reports® format or Microsoft Excel® format.

The report manager allows you to preview and print the protective device setting in different formats including the PDF.

The Excel Device Settings Report provides tabular format with advanced reporting capabilities

Comparison of revision data such as existing versus suggested settings
Sorting and filtering options such as device settings report based on substation / bus IDs.

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.
