To verify that CT saturation will not cause mis-coordination with other protection devices a study needs to be performed, which requires CT modeling. This paper compares different CT computer modeling techniques. Models of a 1200/5 A CT were developed using electromagnetic transient type programs. Simulation results were compared against laboratory tests.<br><br>Published in:<br>Power Engineering Society Summer Meeting, 2002 IEEE (Volume:3 )<br><br>Date of Conference: 25-25 July 2002<br><br>Page(s):<br> 1084 - 1089 vol.3 <br>Print ISBN:<br> 0-7803-7518-1 <br>INSPEC Accession Number:<br> 7554730 <br><br>Conference Location :<br> Chicago, IL, USA <br>Digital Object Identifier :<br> 10.1109/PESS.2002.1043427 <br><br>
