C37.241 - IEEE Draft Guide for Application of Optical Instrument Transformers for Protective Relaying

This document offers guidance on the application and use of optical voltage and current sensor systems for protective relaying, covering selection, installation, testing, and operation of the sensors. This Guide provides information on optical voltage and current sensing technologies, and a number of performance parameters including: accuracy, bandwidth, noise, stability, and impact of temperature and vibration. The Guide also covers interface requirements of optical sensor systems, a number of their applications, relevant installation and commissioning, testing, reliability and redundancy matters, as well as a comprehensive treatment of the relevant industry standards.
