IEEE C37.116-2007

This guide describes the application of protective relays on transmission-line series capacitors and provides alternative approaches to the design, testing, and maintenance of protective relays based on the latest knowledge and the application experience of the industry. This guide will also cover issues related to the reliability of the protection system. The protection and control of distribution system series capacitors and application of variable series capacitors, such as thyristor-controlled series capacitors, are not covered in this guide. The purpose of this guide is to provide the reader with ample discussion of the protection issues related to series capacitor bank design. Applications of series capacitors are sufficiently diverse that protective relay engineers need some guidance on the reasons and considerations for different protection and control schemes. This guide is intended for engineers involved in the areas of protection specifications, evaluation, and operation of series capacitor banks. New IEEE Standard - Superseded. The application of protective relays on transmission-line series capacitor banks is covered. The purpose of this guide is to provide the reader with ample discussion of the protection and control issues related to series capacitor bank installations. Specific examples related to protective functions and testing procedures are provided.
