Applies to both capacitor units and capacitor banks intended to be used connected in series with an a.c. transmission or distribution line or circuit forming part of an a.c. power system having a frequency of 15 Hz to 60 Hz. Focuses primarily on transmission application. The series capacitor units and banks are usually intended for high-voltage power systems. This standard is applicable to the complete voltage range. This standard formulates uniform rules regarding performance, testing and rating, formulates specific safety rules and serves as a guide for installation and operation.
