Abstract
Remote indication devices are each a combination of electrical parameter measurement circuitry, a CPU, and a communication device. Each remote indication device is electrically or electromagnetically coupled to a power distribution circuit conductor to monitor the current flowing in the conductor. The monitored conductor may be an energized power line (“phase”), or a current return line (“neutral”). In either case, the direction of power transfer at each measurement point can also be monitored by each remote indication device. Each remote indication device processes the monitored electrical current information to convert it into a form suitable for data transmission. The information is then presented to a monitoring station. The monitoring station collects and analyzes the electrical current information from the plurality of remote indication devices and is programmed to identify one or more particular power line segments that appear to have a fault.
