ETAP Star device protection and coordination program provides an intuitive and logical approach to time-overcurrent analysis with features and capabilities such as fully integrated user-interface, true-to-the-form protective devices modeling, extensive validated and verified device library, embedded analysis modules, and rule-based designed. Star's sequence-of-operation evaluates, verifies, and confirms the operation and selectivity of the protective devices for various types of fault for any location right from the system one-line diagram.

|
| With ETAP Star, not only can you work with the time-current curves, you can also determine the operating time of protective devices simply by placing a fault on the one-line diagram. |
| |
| Coordinate via One-Line Diagram |
- Graphically place a fault anywhere on the one-line diagram.
- Automatically calculate & display the fault current contributions on the one-line diagram.
- Determine the operating time & state of all protective devices based on the actual fault current contribution flowing through each individual device.
- Globally view post fault actions & associated operating time via a tabulated Event Viewer.
- Graphically examine the operation of protective devices via the one-line diagram.
