Abstract

Forward<br>(This introduction is not part of IEEE Std C37.110-1996, IEEE Guide for the Application of Current Transformers Used for Protective Relaying Purposes). <br>This guide was prepared by the Guide for the Application of Current Transformers for Relaying Working Group of the Relay Inputs Sources Subcommittee of the IEEE Power System Relaying Committee. The guide is intended to assist relay engineers in understanding the operation of current transformers and their selection and application to specific relay protection schemes. <br>At the time this guide was approved, the working group membership was as follows: <br><strong>M. W. Conroy</strong> , <em>Chair </em><br><strong>B. D. Nelson</strong> , <em>Vice Chair</em> <br>B. Bozoki <br>J. W Chadwick, Jr. <br>G. K. Clough <br>P. R. Drum <br>L. L. Dvorak <br>I. O.

Cookson <br>Chester C. Taylor <br>Rochelle L. Stern <br><em>IEEE Standards Project Editor</em><br>Scope<br>This standard describes the characteristics and classification of current transformers (cts) used for protective relaying. It also describes the conditions that cause the ct output to be distorted and the effects on relaying systems of this distortion. The selection and application of cts for the more common protection schemes are also addressed.
