Abstract
A component of an electrical system capable of operation at any of two or more different nominal normal operating voltages is protected from a transient overvoltage condition by an apparatus having at least one phase-to-ground array of surge protection devices (SPDs) connected in series with one another to define a series of tap points on opposite sides of the SPDs and having at least two sets of electrical conductors for coupling the electrical system to a user-selectable one of the tap points which corresponds to a desired one of the nominal operating voltages. An array of capacitors connected electrically in series with one another is connected between each of the tap points and a monitoring circuit to provide impedance for dropping each nominal operating voltage to a suitable voltage for powering the monitoring circuit with low energy loss.
