Development of a digital data acquisition system for localised power loss measurement in electrical machines

Computer aided instrumentation is now firmly established. Techniques for data collection and analysis used in experimental situations generate large amounts of information. Therefore, careful design of computer aided data acquisition for parameter measurement is of greatest importance. The development of a full automated system for localized power loss measurement is described. In particular, the interface method is rigorously examined and potential source of measurement errors are outlined. The performance of the system is compared to a commercialised data logger
