Mechanical over pressure protection device with integrated directional discharge outlet. Provides pressure relief and insulating fluid containment (requires optional piping) on transformers and load tap changers during over pressure conditions. Automatically reseals once pressure has fallen.
Features
- Dual spring loaded valve for quick operation and reseal after a pressure situation
- 50% higher flowrate than the LPRD for increased tank protection during an over pressure event (12600 SCFM)
- Utilizes the same bolt pattern as the LPRD and industry standards enabling direct replacement
- Standard integrated directional shield with 8 inch diameter outlet to maximize flow rate and control hot oil and gas discharge
- Reduces risk to environment, surrounding assets, and people in the immediate area when used in conjunction with piping kits
- Variety of optional piping kits, flanges, and animal screens are available from Qualitrol to divert hot oil
Options
- Operating pressure, Gasket material, indicator style
- Up to 2 latching or momentary switches (single or double pole form C, high DC, or low current gold contacts)
- Electrical connection style
- Gas bleed system
- Stainless steel piping and body option
Applications
For over pressure protection on critical oil filled transformers, load tap changers, and other related electrical apparatus for maximum safety and environmental protection.
