In harbors, imposing cruise ships and even passenger ships or military and civilian ships need electricity when they arrive at the quayside.
Generally, the crews leave the engines running, which causes significant pollution and increases the risk of material and human accidents.
Today, harbors are increasingly equipped with connection terminals. This connection system requires an earthing resistance.
Boats can thus connect and be supplied with electricity directly in contact with these connection terminals.
The MALT resistors protect the transformer which is able to supply the necessary electricity.
The marine earthing system
A controlled high conductivity potential equalization link, such as a naval earthing system is recommended.
The navalearthing system is an effective method of risk reduction and explosion protection, in addition to flange insulation. This system ensures a higher level of safety on the ship and on land.
