The VDI-32 galvanic isolator from Victron Energy (MPN GDI000032000) plays a crucial role in preventing electrolytic corrosion. It blocks all low-voltage DC currents that enter your boat via the shore power ground cable and could potentially cause corrosion on underwater metal parts such as the hull, propeller, shaft, and other components. The internal structure of the galvanic isolator consists of two diodes connected in an anti-parallel arrangement. This configuration allows the diodes to conduct current in both directions, but only when a certain voltage threshold is exceeded. The voltage at which the diodes conduct is 1.4 Vdc.
The isolator is installed directly behind the 230 V connection of your boat. The forward voltage of the galvanic isolator is higher than the potential difference between metals. This means that the voltage does not allow a current to flow 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.
