The Application Research on the Automation of Power Transformer´s Temperature Rise Test

Based on the condition of the test of transformer temperature rise, this system is designed for the auto-control of the test process. With the DSP technique, electrical parameter monitoring and the temperature measurement are integrated in the system. Moreover, with the DSP technique, the test process will be carried on by auto-control. Meanwhile, the program that operates on personal computer is developed by VC++6.0. Utilizing the personal computer´s preponderance, this system may cooperate with personal computer to handle data and automatic control more conveniently. Then artificial intervention in test has been decreased. Further, accuracy of measurement and auto-control level of the temperature rise test process has been heavily improved.
