摘要： A fault indicator for indicating the occurrence of a fault in an electrical conductor is reset at a predetermined time after the fault is detected, such as about 4 hours. The fault indicator has a housing, a high capacity battery, a fault sensor, a display for indicating a fault condition, and a programmable controller with a sleep state that draws low quiescent current. As a result the battery is expected to last the lifetime of the fault indicator. The fault indicator may optionally include current inrush restraint and/or voltage inrush restraint to inhibit the controller from activating the display to the fault indicating condition during the inrush conditions. The electromagnetic field about the conductor causes an electrostatic sensor to develop a differential voltage signal between two electrodes of different areas for the voltage inrush restraint circuit. Auxiliary contacts are provided to remotely monitor the fault indicator.
