ABSTRACT:
In a power supply system having a grounded neutral and supplying service equipment through a distribution transformer, a ground voltage suppression device comprises a saturating inductor or like non-linear impedance device connected between the secondary neutral conductor and a normal ground conductor so as to define therewith a neutral-to-ground current path which presents a high impedance to current flow for applied voltages up to a predetermined level.
