Abstract: This paper compared and analyzed the different content between the current standard GB/T 11022—2020 for high-voltage electrical appliances and the temperature rise test in the void GB/T 11022—2011.The article expressed the differences between the new and old standards of many clauses, such as the three-pole series connection, the permissible temperature rise limitation, the surrounding environment,etc.The results might help quality management staff, product designers, and laboratory testing personnel to understand and use the new version of the standard. Furthermore, it establishes a technical foundation for conducting the temperature rise test regulations.
Key words: temperature rise test; three-pole series connection; temperature rise limit; proximity effect
