This standard applies to capacitors rated 216 V or higher, 2.5 kvar or more, and designed for shunt connection to ac transmission and distribution systems operating at a nominal frequency of 50 or 60 Hz. Service conditions, ratings, manufacturing and testing are covered. The 2002 revision added significant new requirements for units applied in fuseless and internally fused capacitor banks. Currently, suggestions are being collected for the next revision of IEEE 18.
