Description Patented mechanical device for detection of sudden pressure events based on the rate of pressure rise and safe limits established by transformer manufacturers. When a dangerous pressure

Qualitrol 900/910 Rapid pressure rise relays

Protection and detection of dangerous sudden pressure changes Devices calibrated to quickly alarm or trip during rapid pressure rise changes. Actuation only occurs based on rate of pressure rise and will

Eliminate problematic and momentary relay actions

For use on both oil (900 series) and gas (910 series) type transformers. De-energizes transformer in the event of a sudden pressure spike that could cause harm to equipment and personnel.

Qualitrol 900/910 Rapid Pressure Rise Relays (RPRR)

Protect transformers with 900/910 Rapid Pressure Rise Relays, delivering fast response to sudden pressure rises, improved reliability, and enhanced safety.

Qualitrol 900/910 Rapid Pressure Rise Relays (RPRR

When a dangerous pressure rise has been detected, the Qualitrol rapid pressure rise relay (RPRR) will change state. This can be used as an alarm or trip signal to minimize the potential of transformer

QUALITROL RPRR: Transformer Protection Relay

Explore the QUALITROL 900/910 RPRR datasheet for rapid pressure rise relays. Protect transformers with advanced pressure detection.

Protection and detection of dangerous sudden pressure changes

For maximum protection, single channel or multi-sensor QUALITROL 930 electronic pressure monitors are available. Typically used in the most critical situations, these monitors add continuous pressure
