Victron Energy galvanische scheider VDI-64 A (GDI000064000)

The Victron Energy VDI-64 galvanic isolator plays a crucial role in preventing electrolytic corrosion.

It blocks all low-voltage DC currents that enter your boat via the shore power earth cable and thus 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 anti-parallel arrangement. This configuration allows current to flow 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. 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.
