Rapid pressure rise relays are designed to respond to rates of pressure change above predetermined safe limits set by the transformer manufacturer.
The purpose of this device is to detect a fault in a transformer quickly, while the pressure is still increasing and before the destructive effects of overpressure triggers the pressure relief device. The RPRR switches a set of contacts to indicate that it has detected a fault.
The RPRR is designed not to respond to normal pressure variations caused by temperature variation, mechanical shock and vibration or pump surges.
