ETAP Star™ is an easy-to-use, interactive, and powerful platform for overcurrent protection and coordination studies. Supported with 100+ thousands of verified and validated protective device and equipment library models from manufacturers across the world, simulation and analysis of any network are at your fingertips.

Getting Started - ETAP Protective Device Coordination (Star) 1 © 2009 Operation Technology, Inc. Viewing a TCC in Star . This tutorial provides a brief overview of the basic operation of the Star Protective Device Coordination module. It will cover how to create a new Star View and how to add a new device to an existing Star View.

In this article, we will complete our overcurrent coordination series with a sample coordination study using ETAP Star Coordination. The example is taken from the book “Protective Relaying Principles and Application” by J. Blackburn.
