Galvanic Isolator VDI 16
Galvanic Isolator VDI 16
The galvanic isolator prevents electrolytic corrosion. It blocks the low-voltage direct currents that enter your boat through the shore power connection's ground wire. These currents can cause corrosion of the boat's underwater metal parts, such as the hull, propeller, shaft, and so on.
The galvanic isolator consists internally of two diodes connected in antiparallel fashion. In this circuit, diodes allow voltage to pass in both directions, but only above a certain threshold voltage. The voltage at which a diode begins to conduct is approximately 1.4 Vdc.
The isolator is installed directly behind your boat's 230V connection. The forward voltage of the galvanic isolator is higher than the potential difference between metals. Therefore, this voltage cannot conduct current, and the galvanic isolator prevents the flow of an electrolytic current. However, if there is a (higher) fault voltage in the AC circuit, the diodes will allow current to flow, and the residual current device (RCD) will break the circuit.
