Develop, recommend and establish standards on protective relaying practices which are compatible with the electrical environment, including but, not limited to; relay withstand capabilities to electromagnetic interference, characteristics and performance of instrument transformers, testing procedures, applications, performance criteria, and definitions of relays and relay systems. Evaluate and report on pertinent aspects of protective relaying not addressed by other PSRC Subcommittees. Maintain applicable protective relaying standards.

I2Terminology Review Working GroupMal SwansonFred FriendReview drafts of PSRC publications for proper terminology, abbreviations and symbols; and to recommend additions and changes to the IEEE database as appropriate.
I4IEC Advisory Working GroupEric UdrenJay GosaliaDevelop comments and votes for USNC of IEC on TC 95 (Measuring Relays and Protection Systems) standards projects and drafts. Report to PSRC on IEC Standards development.
I23Revision of C57.13.1 – Guide for Field Testing of Relaying Current TransformersBruce MagruderWill KnapekCorrect errors, update with new test methods and equipment.
I24Use of Hall Effect Sensors for Protection and Monitoring ApplicationsJim NiemiraJeff LongDevelop a Report on the Use of Hall Effect Sensors for Protection and Monitoring Applications. The report will discuss the technology and compare with other sensing technologies.
I26Review and Expand Transaction Paper on Mathematical Models of Current, Voltage, and Coupling Capacitive Voltage TransformersMike MeisingerSteve TurnerRecommendation to update and expand mathematical models of instrument transformers and transducers, including interface electronics such as merging units, for use in both off-line and real time transient simulation. There are now new transducer types such as optical, Hall Effect and Rogowski coils in addition to improved models for conventional CTs, VTs and CVTs.
