Galvanic insulator VDI-16, VDI-32 and VDI-64
The galvanic insulator prevents electrolytic corrosion. It blocks low-voltage direct currents,
which enter your boat via the shore power earth cable. These currents can cause corrosion on the metal parts
of the boat under water, such as the hull, propeller, shaft, etc.
The galvanic isolator consists internally of two diodes that are connected in an anti-parallel manner.
This connection method allows the diodes to allow the current to flow in both directions,
but only when a certain voltage threshold is exceeded. The voltage,
at which the diodes conduct, is 1.4V DC.
The isolator is installed directly behind the 230 V connection of your boat. The forward voltage of the
galvanic insulator is higher than the potential difference between metals. As a result, the
voltage does not allow conduction and the galvanic isolator thus prevents any electrolytic current.
However, if a (higher) fault current occurs in the AC circuit, the diodes allow the current to pass and the
residual current device interrupts the circuit.
