This publication provides in-depth practical knowledge of electrical appliances associated with modern marine starter safety & control circuits. It explains & illustrates the elements of marine switchgear starters, how to take electrical measurements, & the principles of direct on line (DOL) & Star-Delta (Wye-Delta) motor starters. As ships become increasingly automated, problems encountered with the application of automated systems, & the failures of automation & associated processor-based motor starters, may contribute to marine accidents. Marine engineers & ETOs must have a good understanding of automated systems in order to maintain them in an efficient & safe operational condition. This training package should be used to enhance & supplement your knowledge & skills. It will provide familiarisation with a variety of electrical appliances that are part of, or associated with, modern marine starter safety & control circuits.
