Ten presentations made by members of the IEEE Task Force on Transformer Tank Rupture and Mitigation over a course of four Transformer Committee meetings have been summarized. The task force was established in 2005 with an aim to review the current state of practice and knowledge for transformer tank rupture and mitigation, as well as to determine if this issue has been adequately covered by existing IEEE standards. The mechanics of transformer tank rupture, current IEEE standards on this issue, as well as various methods for preventing or mitigating tank rupture were presented and discussed. There were 81 registered members in the Task Force. The aim of this paper is to provide a description of all existing methods and technologies to prevent or mitigate transformer tank rupture. The paper does not endorse any particular product or method.
