Faulted circuit indicator with fault characteristic detection and display
First Claim
1. A faulted circuit indicator comprising a housing, a current acquisition circuit disposed within the housing and adapted to monitor current within a power line, and a monitor circuit for determining when a fault has occurred on the power line, the monitor circuit in communication with the current acquisition circuit and disposed within the housing, the faulted circuit indicator further comprising:
- i) a plurality of lamps coupled to the monitor circuit and disposed such that at least two lamps are visible from any determined angle of approach to the faulted circuit indicator as installed on the power line; and
ii) said monitor circuit driving the plurality of lamps in a first predetermined flashing pattern, the first predetermined flashing pattern indicating a direction to the fault relative to the faulted circuit indicator.

Abstract
A display for a faulted circuit indicator is disclosed. A plurality of light-emitting diodes is arranged so that at least two diodes are visible to a person approaching the faulted circuit indicator from a determined angle of approach. When a fault is detected, the faulted circuit indicator flashes the plurality of light-emitting diodes in a progression pattern to indicate the direction to the fault relative to the faulted circuit indicator.
