Abstract

A surge protection system having a plurality of surge protection devices for the protection of a power line. Each of the surge protection devices may be in either a ready state in which the surge protection device provides surge protection or an inoperable state in which the surge protection device does not provide surge protection. The surge protection devices provide a level of surge protection which is based upon how many of the surge protection devices are in the ready state and how many of the surge protection devices are in the inoperable state. The surge protection system includes means associated with the surge protection devices for generating a signal indicative of the level of surge protection, and means coupled to the generating means for displaying a visual indication of the level of surge protection. The surge protection system may also be provided with means for sensing a voltage on the power line and means for generating a visual display indicative of the voltage. The system may also include means for determining when the sensed voltage varies from a nominal voltage by a threshold amount, such as means for determining voltage sags, swells, fractional cycle dropouts, and outages. When an outage is detected, the system may store data relating to various voltage conditions in a nonvolatile memory.
