IEEE PSRC Committee

The IEEE PES Power System Relaying Committee has recognized the impact of non-conventional instrument transformers on protection and control systems and has established working groups to analyze the issues and guide our community regarding their applications to relaying.
This work has resulted in the publication of IEEE C37.235-2007 - IEEE Guide for the Application of Rogowski Coils Used for Protective Relaying Purposes and IEEE C37.241-2017 - IEEE Approved Draft Guide for Application of Optical Instrument Transformers for Protective Relaying. Both guides can be purchased from the IEEE. More
