1. A method, implemented at least in part by a computer system, of detecting contact of an object with a power line that does not sever the power line, comprising:

  • measuring a voltage of the power line;

    detecting a voltage dip of the voltage of the power line that comprises a voltage decrease below a threshold value for a predetermined time followed by a voltage increase to a voltage above the threshold value; and

    determining whether the voltage dip of the power line substantially matches a signature of an object contacting the power line without severing the power line.
