New approach to active electrical quantity measurements in ship power engineering system

This paper shows the presently predominant technology of the measuring equipment construction applied in the main switch-board of ship power station. New proposals of multifunctional measuring instruments based on simple microprocessor devices and adapted to the machinery operation has to be verified by means of specificity of ship's conditions are presented. The main topic is concentrated on short presentation of the methods of active electrical quantity measurements applied in considered simple microprocessor devices and also description of fundamentals of their construction and mode of operation. Finally, simplified error analysis of the instruments under consideration is presented.
