Abstract (en)

[origin: WO9711361A1] An apparatus and method for measuring electrical characteristics of an energy delivery system utilizes a voltage sensitive circuit such as a voltmeter (26), a controllable current source or sink and a microcomputer (22). 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 (26) responds to a voltage developed in response to the current pattern and the microcomputer (22) calculates at least one electrical characteristic of the energy system as a result of the response.
