ADVERC's new Galvanic Isolator rated up to 50A.

 

What does a Galvanic Isolator do?

Galvanic isolation is used in situations where two or more electric circuits must communicate, but their grounds may be at different potentials. it is an effective method of breaking ground loops by preventing unwanted current from travelling between two units sharing a ground conductor. Galvanic isolation is also used for safety considerations, preventing accidental current from reaching the ground through a person's body.

 

Do you need a galvanic isolator?

If you use shore power to provide mains power on your boat. Yes. Not only will it help your boat, it is also considerably safer!

 

Fitting Instructions

If you need help installing our galvanic isolator it can be found in our technical pages (here) and also you can download it as a pdf file for you to keep and use at your leisure by simply clicking here.

 

Testing instructions

ADVERC's Galvanic Isolator interrupts the earth safety circuit. Therefore it must be routinely checked using a multimeter before connecting to shore power and after any rcd trip. We have 8 simple steps to test our galvanic isolator which are in our technical pages (here) and can be downloaded for you convenience as a pdf file here.

ADVERC's Galvanic Isolator is ec/73/23/eec, 89/336/eec and iso 13297 compliant. It therefore complies with the 94/25ec directive.

ADVERC's Galvanic Isolator is incorporated with ADVERC's ONEbox AC consumer unit. Further information about ADVERC's ONEbox AC consumer unit can be found here.

When a boat is connected to a mains shore supply, the shore earth conductor is connected to the boats pending system which includes the hull shafts, propellers and the anodes.

If a second boat is connected to the mains shore supply, then both boats, and any other boats, including a steel jetty, are connected to you via the earth conductor which is bonded to earth.

 

When a potential difference exists in the common earth conductor, galvanic corrosion will take place and your sacrificial anodes will dissolve.

The anodes will dissolve at an alarming rate, if other boats, pontoons or steel jetty are not as well protected as your boat.

 

A galvanic isolator fitted in series with the AC earth conductor maintains a good earth link with the shore but blocks any stray low voltage, DC galvanic current and allows the passage of alternating current associated with the earth conductor.

 

It will not protect against a fault condition if the voltage differential is greater than 1.6v DC.
