Revision Standard - Active.
The application of protective relays on transmission-line series capacitor banks is covered. Ample discussion of the protection and control issues related to series capacitor bank installations is provided to the reader. Specific examples related to protective functions and testing procedures are provided.

This guide describes the application of protection systems on transmission-line fixed series capacitors and provides alternative approaches to the design, testing, and maintenance of protective systems based on the latest knowledge and the application experience of the industry. This guide also covers issues related to the reliability of the protection system.
The protection and control of distribution system series capacitors and application of variable series capacitors or thyristor-protected 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.
