Hardware for an electrical machines laboratory computer data acquisition system

Hardware for an electrical machines laboratory computer data acquisition system is considered. A survey of existing equipment and a study of the role of a computer system in laboratory instruction is made for the UBC electrical machines laboratory. From this, specifications for the hardware required for a data acquisition and processing system are studied and a system configuration proposed. Transducers for measuring voltage and current waveforms on a machine are considered and designed.
The performance of the transducers constructed is evaluated in two sets of measurements. In the first set, measurement error, offset drift, common-mode rejection ratio, and frequency cutoff are measured for the transducer set (by itself). Measurement errors are found to be less than 1% F.S. In the second set of measurements, a system similar to the one proposed for the machines laboratory is tested. Results from this set of measurements indicate that the system design proposed is workable. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
