Safety and
prevention of galvanic corrosion
The Isolation Transformer eliminates any electrical
continuity between AC shore power and the boat. It is essential for safety and
eliminates the need for galvanic isolators and polarity alarms.
Safety is
taken for granted in case of a normal on-shore installation. A fuse will blow
or a GFCI (Ground Fault Current Interrupter) will trip in case of a short
circuit or current leakage to ground. Connecting the ground wire of the
shore-side supply to the metal parts of the boat will result in galvanic
corrosion (see below). Bringing only the live and neutral wire on board results
in an unsafe situation because GFCIs will not work nor will a fuse blow in case
of a short circuit to a metal part on the boat.
Galvanic
corrosion occurs when two dissimilar metals in electrical
contact are simultaneously exposed to an electrically conducting fluid.
Seawater and, to a lesser extent, fresh water are such fluids. In general, the
more active alloy of the couple corrodes preferentially while the less active
(more noble) material is cathodically protected. The rate of galvanic corrosion
is a function of several variables including area ratios, conductivity of the fluid,
temperature, nature of the materials, etc.
It is a
misunderstanding that galvanic corrosion occurs only in metal and
aluminium hulls. In fact it can occur on any boat as soon as a metallic part
(the shaft and propeller) is in contact with water. Galvanic corrosion will quickly
dissolve your sacrificial anodes, and attack the shaft, propeller and other
metal parts in contact with water as soon as the boat is connected to the
shore-side supply. It might therefore be tempting not to connect the ground
conductor: this is however extremely dangerous because GFCIs will not work nor
will a fuse blow in case of a short circuit to a metal part on the boat.
The best
solution to avoid galvanic corrosion and at the same time
prevent any unsafe situation is to install an Isolation Transformer to connect
to the shore-side supply. The Isolation Transformer eliminates any electrical
continuity between shore power and the boat. The shore power is fed to the
primary side of the transformer and the ship is connected to the secondary. The
Isolation Transformer completely isolates the boat from the shore ground. By
connecting all metal parts to the neutral output on the secondary side of the
transformer, a GFCI will trip or a fuse will blow in case of a short circuit.
Soft startis a
standard feature of a Victron Energy isolation transformer. It will prevent the
shore power fuse from blowing due to the inrush current of the transformer,
which would otherwise occur.
It is also
recommended, for optimal safety, to connect the secondary neutral
of the transformer to ground when the boat is out of the water.
