Description

IEEE C37.235-2021 PDF

This guide establishes criteria and requirements for application of Rogowski coils (air-core current sensors) used for protective relaying in electric power systems. The selection and application of Rogowski coils for the more common protection schemes are addressed.
This document provides a guide for application of Rogowski coils used for protective relaying in electric power systems. It is intended to assist the relay application engineer in the correct selection and application of Rogowski coils for protective relaying purposes. It provides guidelines relevant to the performance, operation, testing, and maintenance of Rogowski coil-based current sensors. This guide applies to all types of Rogowski coils used for protective relaying purposes.
Revision Standard – Active. Guidance for the use and application of Rogowski coils (RCs) (air-core current sensors) for protective relaying in electric power systems is described and provided in this guide. The selection and application of RCs for the more common protection schemes are also addressed.
