Dead-line phase identification system and method thereof

A system for identifying an electrical phase of a conductor in a three-phase electrical distribution network having an open circuit condition, said electrical distribution network having a phase conductor with a first end adjacent said open circuit condition and a second end adjacent a transformer, said system comprising:

• a receiver unit having first controller electrically coupled to a first sensor, said sensor being coupled to said second end, said receiver unit having a first communications device coupled to said first controller;
• a transmitter unit having a second controller electrically coupled to a second communications device, said transmitter unit having a switching circuit electrically coupled to said second controller and a conductor coupled between said switching circuit and said first end;
• wherein said first controller includes a first processor, said first processor being responsive to executable computer instructions for transmitting a first signal with said switching circuit onto said first end with said conductor, said first signal having a frequency of less than 45 Hertz;
• and
• wherein said second controller includes a second processor, said second processor being responsive to executable computer instructions for detecting said first signal on said second end with said first sensor and transmitting a second signal with said second communications device to said first communications device in response to detecting said first signal.
