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. ETAP Star is an advanced concept in performing steady-state and dynamic coordination and selectivity of protective devices. This is achieved by utilizing intelligent one-line diagrams, comprehensive device libraries, and an integrated three-dimensional database. Designed and developed by OTI, Star is a fully integrated module within ETAP, with built-in analyses such as short-circuit and motor acceleration.
