Abstract

Temperature-rise test is an important index of power equipment. This paper summarizes the problems inthe process of single-phase temperature-rise test under the high-current of more than 30 k A. Through several simula-tion studies

the corresponding temperature-rise test current loops are constructed

taking into account the productsin the current operating conditions

the combination of the cooling device is selected at the same time. In order to ac-curately determine the performance of the product at large current

the test data measurement system is calibratedand checked in detail. The test data and studied the possible sources of errors in the data acquisition process are ana-lyzed

then the uncertainty analysis is carried out. By studying the many problems in the course of the experiment

itprovides some reference and useful guidance for the relevant testing lab and the manufacturers.
