Transformer pressure relief devices protect oil-immersed transformers against excessive internal tank pressure caused by electrical faults or abnormal operating conditions. Designed to open rapidly when a specified pressure threshold is reached, these devices release excess pressure and help reduce the risk of tank damage. Available in different sizes, pressure settings, and mounting configurations, pressure relief devices can be supplied with optional electrical signaling contacts for integration with transformer protection systems.
