Pressure Relief Device In Transformer

Prd pressure relief device is a device which is used for avoiding high oil pressure builds up inside the transformer during fault conditions.
Pressure relief device in transformer. An internal fault in an oil filled transformer is usually accompanied by overpressure in the transformer tank. The prd allows rapid release of excessive pressure that may be generated in the event of a serious fault. This device is fitted with an alarm trip switch. Mechanical over pressure protection device provides pressure relief on transformers during over pressure conditions automatically learn more.
If the pressure cannot be externally discharged there is a danger that the transformer could explode and potentially cause harm and damage. It is fitted on the top of the main tank. The pressure relief device limits the tank overpressure and reduces the risk of tank rupture and uncontrolled oil spill which might also cause a fire. The simplest form of pressure relief device is the widely used frangible disk.
