Abstract: The traditional equipment of temperature-rising test has low intelligentized capability in measurement and recording. The system cannot record data during test process completely to meet the demands for follow-up researching. The paper studied a measuring system of temperature-rising test to realize the whole process record and the high accuracy data sampling and disposing, and put forward the stable prediction algorithm to estimate the future value of temperature rise with the temperature-rising data during the period of one to three times of time constant, which saved a large number of research test time. Experimental results show that the system meets the requirements of electrical equipment of research tests and type tests.
Key words: temperature rise test; digital measuring; prediction algorithm; precision
