Additionally in case of external fire, it is extinguished within 30 seconds maximum. Nitrogen gas occupies the space created by oil drain and acts as an insulating layer between the top layer of oil in the transformer tank and oxygen in the atmosphere.

Transformer Conservator Isolation Valve (TCIV) blocks the passage of oil and isolates conservator oil thereby preventing conservator oil drain during operation and preventing escalation in the event of fire.
