C37.90.1-1974 - IEEE Standard Surge Withstand Capability Test For Proctective Relays and Relay Systems
Two types of design tests for relays and relay systems that relate to the immunity of this equipment to repetitive electrical transients are specified. Test generator characteristics, test waveforms, selection of equipment terminals on which tests are to be conducted, test procedures, criteria for acceptance, and documentation of test results are described. This standard has been harmonized with IEC standards where consensus could be reached.
C37.110-2007 - IEEE Guide for the Application of Current Transformers Used for Protective Relaying Purposes
Revision of IEEE Std C37.110-1996. The characteristics and classification of current transformers (CTs) used for protective relaying are described. This guide 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.
C37.110-2007/Cor 1-2010 - IEEE Guide for the Application of Current Transformers Used for Protective Relaying Purposes Corrigendum 1: Corrections to Equation 18 and Equation 19
Corrigendum to IEEE Std C37.110-2007. Errors in Equation (18) and Equation (19) are corrected by this corrigendum.
