following calculation can be used to calculate the capacitive reactance
of a single phase single or double bushing capacitor commonly
used on medium and high voltage capacitor banks. Use Table one when
the capacitor voltage and kvar are known. Use Table two when
the system frequency and the capacitance of the capacitor are known.
should noted that in accordance with IEEE Std. 18-1992, capacitor
units should not give less than 100% nor more than 115% (110% for
capacitor units manufactured in conformance with IEEE Std 18-1992
after the year 2000) of rated reactive power at rated sinusoidal
voltage and frequency, measured at a uniform case and internal temperature
of 25C. Acutal values tend to be close to +2% of nominal.
