Examining the Effects of CT Saturation on Substation Protection
Tony Giuliante, President, ATG Consulting, Inc.
Don’t miss this exceptional opportunity for professional development. Dynamic presenter Tony Giuliante, President, ATG 
Consulting, Inc. and long-time analyst of trends in the protective-relaying industry will lead this exciting and practical full-day seminar.
The objective of the seminar is to examine the effects of CT saturation on substation protection. Techniques for creating COMTRADE files for analysis and relay playback testing will be presented. Students will learn the COMTRADE standard, the reasons CTs saturate, and how CT saturation affects bus, transformer and breaker failure protection schemes. The IEEE-PSRC CT saturation spreadsheet calculator will be presented and modified to create COMTRADE files. A DC offset primary current will be created and its waveform presented to CT models where the CT saturation parameters can be varied to produce CT saturation effects. Misoperations caused by CT saturation for bus, transformer and breaker failure protection will be described.
