What is nitrogen hydrogen method of cooling!
Outrageous answer!
100mva transformer is cooled by ofaf. Oil forced,
air forced. You have pumps for circulating the oil
from the main tank to the radiators, and then fans
to cool the radiator banks. There is no such method
of nitrogen+hydrogen cooling of transformers.

Answer / khalid hussain shaikh
THIS TYPE OF HEAVY POWER TRANSFORMER COOLED BY THE FOLLWING
PROCESS.
1. ACTUALLY OIL IS THE MAIN INSULATION MEDIUM BETWEEN CORE
AND TRANSFORMER BODY.
2. OIL CONDUCTS HEAT FROM CORE/ WINDING TO BODY AND
RADIATORS.
3. BY METHOD OF ONAF, HEAT OF TRANSFORMER RADIATED BY
COOLING FANS.
4. IN ADDITION TO THIS WITH OFAF, PROCESS HEAVY PUMPS
CIRCULATES TRANSFORMER OIL TO RADIATORS AND FROM RADIATORS,
HEAT FURTHER , RADIATES AND COOLED FROM AMBIENT
TEMPERATURE.
