1. A method of measuring electrical characteristics of an electrical energy delivery system, including:

  • providing a voltage sensitive circuit and a controllable current source or sink;

    controlling said one of a controllable current source and a controllable current sink with a microcomputer in order to apply at least one predetermined current pattern to or sink at least one predetermined current pattern from at least a portion of an energy delivery system;

    responding with said voltage sensitive circuit to a voltage developed in response to the current pattern being applied or sunk; and

    calculating a value of at least one electrical characteristic of said energy delivery system as a function of said responding.
