scope:

This guide describes measures that may be taken to help mitigate tank rupture of energized liquid immersed power transformers and reactors due to internal electrical faults. This guide does not cover the release of insulating fluid or insulating fluid mist due to failure of the following components: load tap changer compartments, bushings and their turrets, conservator tank, piping, valves, pumps and radiators.

Purpose

This guide describes the current state of knowledge of the relationship between tank rupture and such variables as arc energy level, hydraulic pressures and tank pressure withstand. Also described are various measures that transformer users and manufacturers may take in system design, product design, monitoring devices, signaling devices, and insulating fluid choices that can help mitigate tank rupture.
