IEEE 824-2025

This standard applies to outdoor series capacitor banks and to the major components of a bank that are required to form a complete system for the insertion of capacitors in series with a transmission line. These major components include capacitors, varistors, bypass gaps, bypass switches, discharge current limiting reactors, insulated structures, and protection and control systems. This standard defines the major requirements for the bank and these components. Design and production tests for all of the components are outlined. Disconnect switches associated with the series capacitor bank are not discussed in detail. This standard applies to fixed series capacitor banks where the inserted reactance is primarily established by the reactance of the capacitors. Not included in this standard are power electronic devices for the insertion or bypassing of the bank. In addition, series capacitor banks applied to distribution circuits are not within the scope of this standard.

The purpose of this standard is to provide the basis for the design, manufacturing, and testing of fixed series capacitor banks and associated equipment.

Revision Standard - Active. An update to IEEE Std 824™-2004 is represented by this standard. Series capacitor bank component and bank duty cycle ratings, equipment insulation levels, protective functions, component testing, instruction books, nameplates, and safety are covered in this standard.
