A measurement method of voltage properties on main switchboard busbars - tools and preliminary results

Abstract

In this paper preliminary and exemplary results are presented of voltage analysis on busbars of the main switchboard. Special attention was paid to voltage and its frequency deviation from their nominal values as well as to different voltage waveform distortions. The research contains measurement results of two electrical power systems: of a ro-ro ship and ferry ship. The analysis was carried out offline on the basis of voltage samples from different states of ship exploitation. The analyzed electrical power systems and measurement devices are also described.
