ETAP Star device protection and coordination program provides an intuitive and logical approach to time-overcurrent analysis with features and capabilities such as graphical user-interface, true-to-the-form protective devices modeling, extensive validated and verified device library, embedded analysis modules, integrated and rule-based design.
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 one-line diagram and via normalized Time Current Characteristic curve views.
Using intelligent one-line diagrams, comprehensive device libraries, and a three-dimensional database, ETAP Star offers insight into troubleshooting false trips, relay mis-operation and mis-coordination. |
