Neutral Grounding Resistors (NGR) are the most rational solution, both from the technical and the economical point of view, for grounding any LV, MV or HV electrical system. These resistors are characterized by limiting the fail currents, avoiding damages in transformers and generators, minimizing the maintenance and repairing, both in frequency and in duration and, finally, increasing the working life of all the network components and improving their operative performance.
