The Nitrogen Fire Fighting System is commonly employed in power transformers at power substations. The Nitrogen Injection Fire Protection System (NIFPS) protects against explosions or potential oil fires in the case of arcing caused by internal or external faults in transformers' oil tanks.
| Parameter | Specification |
|---|---|
| Fire extinction period from commencement of N2 injection | 30 secs (Max.) |
| Fire extinction period from activation of system | 3 minutes (Max.) |
| Fire detector's (quartz bulb) heat sensing temperature | 141°C |
| Heat sensing area per detector | Up to radius of 800 mm |
| Transformer Conservator Isolation valve setting | 60 ltr / min (Minimum) |
| Capacity of Nitrogen Generator | 68 ltr (Minimum) with N2 storage tank for 10 m³ Nitrogen gas |
| Power Supply | 230 VAC |
Low investment cost as compared to other conventional fire fighting systems available in the market.
Very low post fire damage and no secondary damages to the transformer or surrounding equipment.
Minimum maintenance and running cost, making it highly economical over the entire lifecycle.
System performance remains unaffected by climatic conditions — suitable for all weather environments.
Suitable for both indoor and outdoor installation at power substations and transformer yards.
Minimum space requirement compared to conventional water-based or foam-based fire fighting systems.
Multi signals for activation eliminate false alarms and ensure reliable fire detection response.
Allows system testing on operational transformer — not possible with conventional fire fighting systems.
No moisture absorbing inside the transformer due to the continuous presence of nitrogen gas.
Great saving in cost due to absence of moisture, preventing insulation degradation and oil deterioration.
Fully automatic, unattended and a foolproof system with manual/automatic and local/remote control options.
No water reservoir or major civil work required, reducing installation time and infrastructure cost.
Prevents transformer explosion ensuring the power system remains functioning during fault conditions.
Prevention of unplanned outages, ensuring continuous power supply and grid stability.
Considerable savings in operational costs, equipment replacement and downtime over the system's lifespan.
Improves overall power system reliability and safety for critical transformer infrastructure.
