IEEE 824-2004 pdf download IEEE Standard for Series Capacitor Banks in Power Systems
1.Scope
This standard applies to outdoor series capacitor banks and to the major components of a bank that arerequired to form a complete system for the insertion of capacitors in series with a transmission line. Thesemajor components include capacitors, varistors, bypass gaps, bypass switches, discharge current limitingreactors, insulated structures, and protection and control systems. This standard defines the majorrequirements for the bank and these components. Design and production tests for all of the components areoutlined. 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 bythe reactance of the capacitors. Not included in this standard are power electronic devices for the insertion orbypassing of the bank. In addition, series capacitor banks applied to distribution circuits are not within thescope of this standard.

3. Definitions
The meaning of other terms used in this standard shall be as defined in The Authoritative Dictionary ofIEEEStandards Terms,Seventh Edition (B4].
3.1 ambient temperature: The temperature of the air into which the heat of the equipment is dissipated.
3.2 bypass current: The current flowing through the bypass switch, protective device, or other devices inparallel with the series capacitor.
3.3 bypass gap: A system of specially designed electrodes arranged with a defined spacing between them.in which an arc is initiated to form a low-impedance path around one segment or a subsegment of the seriescapacitor bank. The conduction of the bypass gap is typically initiated to limit the voltage across the seriescapacitors and/or limit the duty to the varistor connected in parallel with the capacitors. The bypass gapincludes the electrodes that conduct the bypass current, the triggering circuit (if any), and an enclosure
NOTE-See Figure 1.8
3.4 bypass switch: A device such as a switch or circuit breaker used in parallel with a series capacitor ancits protective device to bypass or insert the series capacitor bank for some specified time or continuouslyThis device shall also have the capability of bypassing the capacitor during specified power system faulconditions. The operation of the device is initiated by the capacitor control, remote control, or an operatorThe device may be mounted on the platform or on the ground near the platform.
NOTE-See Figure 1.
3.5 capacitor element: The basic component of a capacitor unit consisting of two electrodes separated by adielectric.
3.6 capacitor rack: A frame that supports one or more capacitor units.
