Protection & Selectivity Path Detection Software

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

Protection Zone Viewer

Protection Zone Viewer displays the protection zones and selectivity paths for selected elements

on one-line diagram and facilitates the protection and coordination studies.

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.

Path detection tools include:

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
