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.
