Abstract:
A faulted circuit indicator (FCI) for providing an indication of a fault on a monitored conductor, determining whether the FCI is near the end of its useful life (or entered into an end-of-life mode) and altering an operation of the FCI if the useful life of the FCI has reached a select threshold. The operation alteration may include an alteration of the display and/or deactivation of certain features and/or functions of the FCI. Thus, the useful life of the FCI will be increased. Further, utility personnel will be more likely to notice that the FCI is in end-of-life mode. The FCI may also include a battery discharge module and a thyristor for discharging the battery for disposal upon decommissioning of the FCI.
