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.
