Abstract

Digital measurement system of electromagnetic disturbances and audible noise of marine drive systems with frequency converters is described. This measurement system allows establishing the synonymous and rational correlation, between electromagnetic disturbances in AC motor supply line and audible noise of the drive system. Thanks to this method, the audible noise reduction can be obtained by attenuation of motor electrical supply harmonics.
