Abstract

A Microsoft Windows based instrumentation and control system has been developed around a generic Intel 80386 microcomputer with an A/D card, counter timer card, stepper motor driver card, and a GPIB port. The computer can control two DC power supplies and the tap position on a three-phase autotransformer. The ratings on the supplies are consistent with the ratings of the 2 kVA AC and DC machines. Data can be downloaded from digital storage oscilloscopes for processing and display. A virtual instrument package has been written that can create, log, and display up to 25 meters. The only analog preprocessing required are voltage dividers, current shunts, and isolation amplifiers. The package is extensible, allowing students to add their own program modules for real-time control
