Interactive Result Viewer

The evaluation results of protective device protection and coordination study are displayed in tabular and graphical format for easy and quick reference.

The Star Auto-Evaluation Viewer highlights detected violations and concerns of equipment protection and device coordination for possible correction and adjustment of protective device settings.

Protection & Coordination Rule Book

Protection rules are applied to evaluate the settings of the protective devices for equipment protection against possible damage. Coordination rules help identify the time-overcurrent conflicts between downstream and upstream protective devices to help you set the optimal setting.

ETAP Star RuleBook offers a set of default rules based on industry standards and guidelines. You can customized and apply different evaluation criteria rules based your company / industry practices.
