IEEE 18-1992 pdf download.IEEE Standard for Shunt Power Capacitors.
Abstract: Capacitors rated 216 V or higher, 2. 5 kvar or more, and designed for shunt connection to alternating-current transmission and distribution systems operating at a nominal frequency of 50 or 60 Hz are considered. Service conditions, ratings, manufacturing, and testing are covered. A guide to the application and operation of power capacitors is included.
Keywords: capacitors, shunt connection, transmission and distribution systems.
IEEE 18-1992 applies to capacitors rated 216 V or higher, 2. 5 kvar or more, and designed for shunt connection to alternating current transmission and distribution systems operating at a nominal frequency of 50 or 60 HZ.
4.2 Abnormal service conditions
If capacitors are required to operate under abnormal service conditions, such as the following, the applica ion should be brought to the attention of the manufacturer.
a) Exposure to damaging fumes or vapors
b)Exposure to conducting or explosive dust
c)Exposure to abnormal mechanical shock or vibration, including earthquakes
d)Exposure to radiated heat from surfaces(other than the sun )that are hotter than the ambient temperature limits for capacitors given in 5.7
e)Mounting and/or arrangement that prevents adequate ventilation
f) Operation in ambient temperatures outside the range specified in 5.7
g)Altitude higher than 6000 ft(1800 m)above sea level(see 6.6.2 and Table 4)
h) Momentary duty exceeding that listed in 8.3.2
I) Service conditions other than those listed in 4.1
