NIFPS (Nitrogen Injection Fire Protection System)

The Nitrogen Injection Fire Prevention System (NIFPS) is an advanced protection mechanism designed specifically for oil-filled power transformers. It works on the principle of preventing tank explosion and fire by rapidly reducing the temperature of the oil and removing oxygen.

  • Preventative Cooling: Upon detecting a fault (such as a Buchholz relay trip or differential relay trip), the system drains a specific amount of oil to create space for nitrogen injection.
  • Stirring Effect: Compressed nitrogen is injected from the bottom of the transformer, creating a stirring effect that cools hot oil by mixing it with colder layers.
  • Oxygen Displacement: Nitrogen forms a blanket over the oil, displacing oxygen and preventing completion of the fire triangle, thereby stopping combustion.
  • Fast Response: An automated, fast-acting system that activates within milliseconds of fault detection to prevent catastrophic rupture of the transformer tank.
  • Environmentally Friendly: Nitrogen is an inert gas that does not contaminate transformer oil or leave residue, allowing easier maintenance after a fault.
