Protection Zone & Path Detection
Star™ Intelligent Protection Zone and Path Detection
Overview
ETAP Star includes intelligent and automatic protection zone and path detection tools that quickly identifies the elements within each zone. The association of these tools with one-line diagram provides fast and easy approach to create Star View TCC (Time-Current Characteristics) and verify overcurrent protection / coordination within any selected portion of electrial network.
Key Features
- Intelligent protection zone detection for any selection on one-line diagram
- Display of the elements with each zone
- Single or multiple selection for creation of Time-Current Curves
- Split of zones into 4 categories
- Branch Zones
- Bus Zones
- Load Zones
- Source Zones
- Filtering capability by zone type and voltage
- Sorting capability based on zone type, connection, and ascending/descending order
- Creation of Star View TCC per zone or single Star View for selected zones
- Append to existing Star View TCC

Path Detection Tool
Path Detection Tools provide an easy way to automatically identify and define protection and coordination / selectivity paths.
Each path selection tool requires that elements be selected in order to determine the path. AC 3-phase or 1-phase elements can be selected on the OLV.
- Extend to nearest source - Once an element is clicked, automatic path detection will extend the selected element to the nearest source
- Shortest connecting path - Selects or highlights the shortest path between two elements
- Extend path by bus level - Path shall be extended by a pre-defined number of bus levels in all directions
