Abstract: This paper describes a fully automated method of measuring the cold and hot resistance of a transformer. The measuring scheme was developed by using a code composer studio (CCS) environment, TMS320F2812 digital signal processor and external interface hardware. The CCS allows a high degree of software modularity and provides the features that are required for sensor zero adjustment, data acquisition through ADC and analysis, and automated presentation of results. Furthermore, the experimental setup described in this paper could be used to obtain the cold and hot resistance of other electromechanical devices. The real-time implementation of cold and hot resistance measured setup and the results from a test on transformer are presented in the paper.

Keywords: measurement systems; hot resistance; cold resistance; transformers; TMS320F2812; digital signal processing; DSP; modular software; data acquisition; electromechanical devices.
