Ship Power System Analysis Based on Safety Aspects

Abstract

-This article analyses the reasons for the reduction of insulating resistance, processes influencing them and isolation diagnostic methods. It provides a short description of electrical safety situation on ships with isolated neutral electrical power systems. It also covers the methods of protecting personnel from electric shock or preventing ignition or arching damage at the fault location with the help of fault current compensation. Principal fault current compensation circuit diagrams are analysed by using the minimum value and time of transient fault current as criteria.

Navigating Human Factors in Maritime Safety: A Review of Risks and Improvements in Engine Rooms of Ocean-Going Vessels

“…Maritime transportation necessitates the usage of nearly all forms of electrical equipment found in industrial facilities. For example, generators, electric motors, switching and distribution equipment, protective devices, semiconductor converters, voltage transformers and power converters, electrochemical converters -batteries, electrical protection, automatic control and diagnostics, reactive power filters, device power restrictions, drivers, couplings, bushings, various distribution boxes, lighting, heater installations, and so on [39].…”
