IEEE C57.13.1 2006 Edition, November 16, 2006 Guide for Field Testing of Relaying Current Transformers
More info
Description / Abstract:
The scope of this guide is to describe field test methods that
assure current transformers (CTs) are connected properly, are of
marked ratio and polarity, and are in a condition to perform as
designed both initially and after being in service for a period of
time.
Annex A describes wiring integrity checks, uses of test jacks and current shorting switch, and relay test equipment.
Annex B illustrates excitation voltage measurement differences between rms responding voltmeters, commonly used under field conditions, and average responding voltmeters commonly used in laboratory tests and also discusses the effect of the source impedance.
Annex C describes the characteristics, and other pertinent information, for optical current sensor systems used with protective relaying. It provides an overview of the components used in an optical sensor system, discusses the differences from conventional CTs, and provides testing information.
Annex D is the bibliography for this guide.
Purpose
The purpose of the guide is to provide information on the current technology for field testing of instrument transformers and to more closely coordinate the information with the other industry standards, for example, National Electrical Safety Code® (NESC®).
