摘要： A faulted circuit indicator utilizes digitized fault indication curves to determine if a fault has occurred in a monitored conductor. Fault indication curves are intended to be similar to trip curves of common power protection devices, and consist of a plurality of associated fault current levels and fault times. The faulted circuit indicator only displays a fault when the current within the monitored conductor exceeds one of the fault current levels for its associated fault time. This results in more accurate fault detection through the ability to distinguish between small and large amplitude faults coupled with the flexability of a fault indicator suitable for use on many different power systems.

摘要： A fault indicator for indicating the occurrence of a fault in an electrical conductor has a housing, a high capacity battery, a permanent fault display for indicating the occurrence of a permanent fault, a temporary fault display for indicating the occurrence of a temporary fault, a current sensor for sensing the load current in a monitored conductor, a microcontroller for determining when a fault condition occurs and for activating the permanent or temporary fault displays. Preferably, each display includes one or more LEDs. Upon detecting a fault, the microcontroller begins flashing the permanent fault LEDs. After a predetermined interval, the microcontroller again senses the load current. If the current is zero, the fault is permanent and the permanent LEDs continue to flash until a timed reset occurs. If the load current is present, the fault is temporary and the temporary LED is flashed until the timed reset. A light sensor is used to detect nighttime conditions, and microcontroller supplies reduced power to the LEDs at that time. Power to the LEDs is supplied in a repetitive pattern consisting of pulses followed by off time. Related methods are also disclosed.

摘要： A fault indicator for monitoring an electrical conductor has a housing, an indicator flag or a light emitting diode (LED) that becomes visible from the exterior of the fault indicator upon the occurrence of a fault, and electronic circuitry for sensing a fault, for actuating the indicator flag or LED to a fault indicating condition and for resetting the indicator flag or LED to a non-fault indicating condition a predetermined time after the fault has occurred. An overload indicator provides an overload indication, such as a fast flash rate, for a predetermined time when an overload threshold is exceeded, and provides a different overload indication, such as a slow flash rate, for a predetermined time when the line current in the monitored conductor falls below the threshold.

摘要： A fault indicator for indicating the occurrence of a fault in an electrical conductor has a housing, a high capacity battery, at least one light emitting diode (LED) visible from the exterior of the fault indicator upon the occurrence of a fault and which may be automatically reset to a non-fault indicating position a predetermined time after the occurrence of the fault, and electronic circuitry for sensing a fault, for actuating the LEDs to indicate a fault and for resetting the LEDs to a non-fault indicating condition a predetermined time after the fault has occurred. The electronic circuitry conserves energy by drawing insubstantial current from the high capacity battery during non-fault conditions. The electronic circuitry may also include in-rush restraint to avoid false tripping of the fault indicator during surges. An inrush restraint circuit has an output signal that is logically combined with a fault indicator signal to disable the fault indicator during inrush conditions. An improved electrostatic sensor senses the electromagnetic field associated with a monitored conductor, provides less susceptibility to affects from adjacent conductors and provides operating power to the inrush restraint circuitry.

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.
