Nitrogen Injection Fire Protection System

Nitrogen Gas Firefighting System

Nitrogen fire fighting system commonly used in power transformers at Power sub stations. Nitrogen Injection fire protection system(NIFPS) prevents explosions or rapture and possible oil fire in event of minor nature of arcing due to internal faults or external faults in transformers oil tanks. In case of rise in Temperature inside Transformer due to various reasons, PLC based NIFPS system receives internal inherent Faults / Feedback / Trip Signals from Transformer Panel. In case of any incident PLC based NIFPS system activates electrically operated Transformer Conservator Isolation Valve / Oil Drain Valve / Nitrogen Injection Valve etc. which Isolate the Oil Conservator Tank from main Tank, drains out oil from Transformer into the Oil Pit and Nitrogen gas is injected which creates a layer rest of the oil to avoid any contact with Atmospheric Oxygen.

ADVANTAGES OF Nitrogen Injection Fire Prevention System (NIFPS)

i) Low investment cost as compared to other conventional system.

ii) Very low post fire and no secondary damages.

iii) Minimum maintenance and running cost.

iv) No climatic effects.

v) Suitable for indoor / outdoor installation.

vi) Minimum space requirement.

vii) Multi signals for activation, eliminates false alarms.

viii) Allows system testing on operational transformer not possible with conventional fire system.

ix) No moisture absorbing in inside the transformer due to presence of nitrogen.

x) Great saving in cost, due to absence of moisture.

xi) Fully automatic, unattended and a fool proof system.

xii) It can be operated manually / automatically, local / remote control.

xiii) No water reservoir or major civil work required.

xiv) Prevents transformer explosion ensuring system remains functioning.

xv) Prevention of unplanned outages.

xvi) Considerable savings. xvii) Improves overall power system reliability.
