Abstract:
1. A system for identifying an electrical phase of a conductor in a three-phase electrical distribution network having an open circuit condition, said system comprising: a first current sensor configured to removably couple with a first phase conductor of said three-phase electrical distribution network distal from said open circuit condition; a first controller electrically coupled to said first current sensor; a first communications device electrically coupled to said first controller; a second communications device operably coupled to receive a signal from said first communications device; a second controller electrically coupled to said second communications device; a power supply electrically coupled to said second controller; a switching circuit electrically coupled to said power supply and said second controller; and, a test conductor coupled to said switching circuit and configured to removably couple with said first phase conductor adjacent said open circuit condition; wherein said second controller includes a first processor, said first processor being responsive to executable instructions for transmitting a first signal on said first phase conductor from said switching circuit through said test conductor; wherein said first controller includes a second processor, said second processor being responsive to executable computer instructions for detecting said first signal with said first current sensor and transmitting a second signal through said first communications device to said second communications device.
