Principle of Operation:
There are two modes of operation viz Transformer Explosion Prevention Mode and Transformer Fire Extinguishing Mode
Transformer Explosion Prevention Mode:
When an internal fault takes place large amount of flammable gases are formed in the transformer tank. As a result the gas relay closes and the electric breaker switches off. There is a pressure build-up inside the tank due to the thermal inertia. Once the pressure exceeds the set value of the pressure relief valve (PRV) the system relives the pressure by draining 10% of oil from the transformer and thereby preventing an explosion and fire. Subsequently the hot oil is cooled by injecting the Nitrogen gas.
Transformer Fire Extinguishing Mode:
When the transformer is on fire, the fire detectors operate along with the gas relay and which trips the electric breaker. As a result the system operates to drain the oil and inject nitrogen gas so as to sufficiently cool the transformer thereby extinguishing the fire and prevent any re-combustion.
The system is recommended as per the Indian Electricity Rules for all transformers and reactors of oil capacity above 2000 liter.
