The supply of electricity constitutes a vital part of society's infrastructure and the demand for reliable distribution of high-quality electricity is ever increasing. With the Ground Fault Neutralizer (GFN) you will be able to meet these demands while still guaranteeing highest possible safety. Earth faults (single phase to ground faults) are the dominating type of fault in an electrical network. Therefore it is of utmost importance that these faults are handled in a satisfactory way. By injecting a phase-opposite current into the neutral, the GFN effectively cancels out the fault current. This interception is exceptionally fast and has no impact on the conveyance of payload over the faulty feeder. Thus, earth faults can be handled without customer outage. The GFN protects all parts of an interconnected grid - from the power transformer over the bus bar and the outgoing feeders down to the last corner of the grid - a truly comprehensive protection scheme. This overall action is accomplished in a very cost efficient way from one point - the neutral.
