Abstract
A fault-tolerant self-indicating surge protector system and methods are presented. An unwanted surge of electrical energy induced by a lightning strike is directed away from a sensitive electrical or electronic component, and the unwanted surge of electrical energy is directed through series connected pairs of varistors. A voltage signal is extracted from a center tap point between the series connected pairs of the varistors, and the voltage signal is monitored for a health of the varistors. A high impedance in a varistor among the varistors is provided for a low voltage across the varistor, and a low impedance in the varistor is provided and the unwanted surge of electrical energy is diverted through the varistor in response to a high voltage across the varistor.
