The object of this Technical Report is to document a method for the sound pressure level measurement on power capacitor units, by which the sound power level of power capacitor units is determined.<\/p>\n

This method is applicable to shunt capacitor units and AC filter capacitor units for AC power systems with a nominal voltage of 1 kV and above and a frequency of 50 Hz or 60 Hz.<\/p>\n

This method also applies to the DC filter capacitor units.<\/p>\n

Other measurements on power capacitor units can be implemented with reference to this method.<\/p>\n
