ETAP Star overcurrent device protection and coordination evaluation software provides an intuitive and logical approach to Time-Current Characteristic (TCC) curve analysis with features and capabilities such as an easy-to-use graphical user interface, accurate protective device modeling, device settings report creation, extensive Verified & Validated (V&V) protection device library, and embedded analysis modules, all within an integrated, rule-based design.

Using intelligent one-line diagrams, comprehensive protective device libraries, and a three-dimensional database, ETAP Star offers insight into troubleshooting false trips, relay mis-operation, and mis-coordination.

Along with plotting protective device operating curves, ETAP Protective Device Coordination software provides tools capable of plotting the starting, inrush, and damage, curves for equipment like motors, transformers, generators, and cables. Offering insight into troubleshooting false trips, relay and breaker mis-operation, and mis-coordination.
