PRD-250 High-Speed Vent
The PRD-250 High-Speed Vent is an advanced pressure relief device designed to mitigate internal overpressure in power transformers. It features rapid-response actuation to prevent catastrophic tank failure events.
PRD-250 Specifications
Operations
Features an ultra-rapid millisecond response time engineered for swift high-energy fault suppression.
Relief Port
Utilizes a 250mm wide-bore discharge aperture to maximize instantaneous volumetric flow capacity.
Pressure Range
Offers versatile, factory-calibrated operating thresholds to meet specific substation pressure requirements.
Visual Status
Includes a high-contrast mechanical semaphore indicator for immediate local identification of activation.
Compliance
Fully compliant with rigorous IEEE C57.12.00 and IEC 60076 global safety and performance standards.
Fast Acting
Rapid Venting Cycle
Utilizes a spring-loaded diaphragm to achieve instantaneous opening during sudden pressure fluctuations.
Safety First
Equipped with dual microswitches to immediately signal the SCADA system when a vent event is triggered.
Easy Setup
The bolt-on design facilitates seamless mounting on standard transformer tank flanges or manhole covers.
Rugged Build
Corrosion-resistant materials and robust seals ensure long-term reliability in harsh grid environments.
