TN-grounding systems for the emerging cold ironing: multiple grounded system vs island system
The commercial routes interconnection in maritime world transport requires common criteria for the standardization of shore connection's rules in port areas. A brief focus on the part 1: High Voltage Shore Connection (HVSC) Systems (IEC-ISO-IEEE 80005-1) has been presented that is an example of global harmonization. This paper reports the cold ironing system issues due to the grounding systems. Several aspects must be taken into account as transferred touch potentials according to the workers safety for interferences due to the ground loops.
