Transformer is among the most expensive equipment located in power plants and substation etc. They generally contain a large quantity of combustible substance, which can spread fire to nearby installations also and caused a power failure and can lead to economic losses. So special attention should therefore be paid for their protection.
The traditional System like "High Velocity Water Spray System/ Co 2 Gas Flooding System" provides
external protection of the transformers and they come into operation once the Fire got initiated around
the transformer for the reason whatsoever or in case transformer already got exploded. Whereas
"Nitrogen Injection Explosion prevention & Fire Protection System” is an internal protection of the
transformer as it prevents the Transformer from its explosion which generally occurs due to over heating/ overloading / winding Short-circuiting or for any earth fault etc.
It prevent the Transformer from explosion.
Nitrogen Gas is inert and does not react with transformer oil. It is completely NonToxic & Non-hazardous.
It provides best cooling effect to the oil inside the Transformer. Forms insulating layer of N2 Blanket on top surface of the oil. Less Cost of Installation & Maintenance.
Environment Friendly.
Best System for the Areas of water Scarcity.
CNF Spray System for External Fire Protection (Optional).
Amechanical interlocking has been provided to ensure that nitrogen injection will not take place into the transformer until the oil drain valve is open.
