Distribution transformer tank pressure study
Abstract
Calculated static pressures are given which may occur within faulted oil filled distribution transformers as a result of arcing and gas generation. Information contained in this report is the result of extensive mathematical study of distribution transformer internal pressure of relatively slow build-up. Even though impact type forces are not considered, the pressure tables can be useful in the design of distribution transformer enclosures. It can be applied by transformer users in reaching a decision to retrofit existing transformers with automatic pressure relief devices, or to modify fusing practices for distribution transformers.
