Abstract

The present invention system includes:(a) in-parallel connection to an incoming power supply of a facility including a hot line and a neutral line, and at least one ground. There are components connected between the hot line and the neutral line in the following order (b) front metal oxide varistor(s) line transient voltage surge suppressor having to suppress undesired power spikes;(c) at least one capacitor of predetermined capacitance;(d) at least two chokes in the form of inductor/metal oxide varistor transformers;(e) at least a second capacitor of its own predetermined capacitance;(f) back metal oxide varistor(S) having a predetermined capability. In preferred embodiments, the metal oxide varistor may be a plurality of varistors in parallel; (g) a failure indicator circuit connected to the transient voltage surge suppressor, including at least one relay, one voltage-surge responsive switch and one indicator signalling component.
