Abstract: Introduction was made to the differences between the new standard GB 1094.2—2013 and the old standard GB 1094.2—1996. Compared with the old standard, the scope of the new standard was only suitable for liquid-immersed transformers. This paper elaborated the temperature-rise test for liquid-immersed transformers and analyzed the differences between the new and old standards about the terms and winding mean temperature rise, test method for temperature rise, annexes and so on, which provides references for the relevant technical personnel.
Key words: transformer; standard; temperature-rise; test; difference
