MULTIPLE COIL CONFIGURATION FOR FAULTED CIRCUIT INDICATOR.

摘要

A faulted circuit indicator (FCI) may use a multiple coil configuration to improve measurements of current flowing through a power line. The FCI may include a fault alert module and a sensor configured to measure a current flowing within a power line based on a first inductive coupling with the power line. The FCI may further include a power supply configured to provide at least one supply voltage based on a second inductive coupling with the power line. The FCI may include a detector/controller module coupled to the fault alert module, sensor, and power supply. The detector/controller may be configured to monitor measurements provided by the sensor, and provide a warning signal to the fault alert module when a fault condition in the power line is detected.
