Electrical Protection in the marine industry is complex by nature with a constant wet environment. Most vessels operate an unearthed electrical system due to the ever present issue of electrolysis. However when it comes to vessels being in a marina or port, the power source is always a normal earthed mains system.
The RVD when installed within a vessel provides an ideal solution for an earthed environment one moment and unearthed the next that is what is the marine example. The risk of harm is significantly reduced with the benefits being improved electrical safety, reduced risk of fire and reduction in electrolysis from the unearthed electrical system onboard the vessel.
