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.
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
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
For over pressure protection on critical oil filled transformers, load tap changers, and other related electrical apparatus for maximum safety and environmental protection.
