Abstract :
Vibration and audible noise generated by power capacitors subjected to nonsinusoidal waveforms are discussed. A study of the relation between the vibration (audible noise generated) and the capacitor current (and voltage) is presented. Capacitor data obtained in the laboratory and in a distribution substation are compared. This investigation confirms that a bank of power capacitors can generate significant noise if the capacitor current contains high frequency harmonics
