Pressure relief devices
Pressure in the transformer is one of the key health parameters that predict early signs of decreased performance or an upcoming failure. Overpressure in the transformer tank can lead to an explosion and a hot oil spill in the surrounding environment. The valve size is proportional to the volume of the oil in your transformer. Choose one of our pressure relief devices to keep the pressure in the transformer under control. It can discharge the overpressure to the exterior very quickly and reduce the risk of tank rupture.
