Proper maintenance of the explosion protected equipment and systems on ships requires special knowledge and skills. It is worth to underline that the explosion protection properties of electrical equipment are generally different from the functional ones. It means that the electrical explosion protected equipment can lose its explosion protected properties and can still work because its functional side is in a good condition and vice versa (only for intrinsically safe solution). From the safety perspective the intrinsically safe measurement line fulfils safety requirements, but from the functional one it can introduce some additional measurement errors. To avoid such situations, the new course under discussion is proposed. The course gives a possibility to improve crewmembers' skills, especially for intrinsically safe solutions.

This paper deals with an analysis of the threats and adequate counter-measures connected with the impact of photovoltaic systems on low voltage grids characteristics. The growing interest in photovoltaic systems use is to be analysed from the perspective, that electrical energy distributed in industrial grids meets the relevant quality requirements in accordance with strictly defined standards.

The paper deals with a key issue, how to limit the hazard and assure reliability, safety and repeatability of operation of selected critical devices protecting electrical power systems. The main research is focused on the incorrect operation of hybrid switches caused by random disturbances of the thyristor gate signals in the electrodynamic drive coil power supply circuit. Firstly, a pilot experiment on the operation of hybrid circuit breaker actuators under random disturbance conditions was carried out and the results are presented. Next, an in-depth operation analysis, based on experimental and simulation research, according to setting conditions of the circuit breaker actuator parameters such as capacitance, voltage and switching time was performed. A simulation study with the use of a field–circumferential model in the Ansys Maxwell program of electrodynamic propulsion of rectilinear motion, which enables energy transfer from the capacitor bank to the actuator coil power supply at selected time intervals, was executed. The study analysed the impact of the discontinuity of energy transfer on the dynamic properties of the actuator and some recommendations for designers and users on how to limit this hazard are formulated.

The content of this paper consists of a presentation and discussion on a case study-based overview of some selected challenges dealing with a problem of power quality on ships. As a consequence, the theoretical considerations are aided by experimental results based mainly on the author’s research team experience and achievements. Two basic aspects, assessment and improvement of power quality are taken into account. In the process of power quality assessment, the existing ambiguities are analyzed and discussed, after that the undertaken measures and challenges to overcome them are presented. The ways of improving of power quality on ships are described and analyzed in two layers: technological solutions and the staff competences. Expectations and challenges for the future based on developments of both, legal and professional aspects are focused on the key question: how to reduce a risk of ship accidents. Finally, the future works as well as the concluding remarks are formulated and commented on.
