Description: This paper deals with the problem of power quality
estimation in ship systems during their exploitation stage. The
exemplary results of experimental research have been shown and
present rules concerning power quality in ship’s networks have been
discussed. Especially, two methods of THD defining have been
compared on the basis of chosen ship voltage waveforms. Further,
some proposals for improving these rules have been laid.
