Generator transformer is one of the important equipment for electric energy metering and relay protection in the power system industry. Its volt-ampere characteristics are closely related to the safe, reliable and economical operation of the generator. Aiming at the shortcomings of the current traditional volt-ampere characteristic test system developed based on 8-bit single-chip microcomputer, this paper uses popular embedded processing technology, selects the cost-effective ARM core processor LPC2214 and the stable real-time operating system μC/OS-Ⅱ as the development platform, and designs and implements the generator volt-ampere characteristic test system. The system mainly includes online testing, parameter setting, data query, serial communication and other functions. This paper completes the software design and development of the above functions, especially the design of the display scheme of the table characteristic curve in the online test function. Based on the in-depth study of the working principle of the display module and the display requirements of the system, this paper improves the table characteristic display method, so that the system can not only display the volt-ampere characteristic curve in real time, but also dynamically display the measurement curve, laying the foundation for the further development of the system. In addition, based on the serial communication function between the system and the host computer, the system virtual environment is realized using the LabWindow/CVI7.0 development platform to meet the user\'s needs for further analysis of the measurement data. After a long period of field testing, it has been proved that the system not only reduces the number of instruments used in traditional testing, but also performs outstandingly in simplifying the test process of generator transformers, increasing the degree of automation of on-site operations, and improving the accuracy of transformer testing, thus creating favorable conditions for improving the correct action rate of generator relay protection devices.
