First Claim
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.

Abstract
An apparatus and method for measuring electrical characteristics of an energy delivery system utilizes a voltage sensitive circuit such as a voltmeter, a controllable current source or sink and a microcomputer. The microcomputer controls the current source or sink in order to source at least one predetermined current pattern or to sink at least one predetermined current pattern from a portion of an energy delivery system. The voltage sensitive circuit responds to a voltage developed in response to the current pattern and the microcomputer calculates at least one electrical characteristic of the energy system as a result of the response.
