Abstract： Dynamic thermal stability test is used to test the ability of electrical products to withstand electrical stress and thermal effect generated by short circuit current. The specifi c requirements and characteristics of the test should be fully understood when carrying out the dynamic thermal stability test in the large capacity test system. Based on the standard requirements and combined with the test experience， this paper discusses the test procedures， operational requirements， risk points and protective measures， providing reference for relevant test personnel.

Keywords： dynamic thermal stability test， short circuit current， electrical stress， thermal effect capability， high capacity test system
