How is a 100 MVA transformer cooled?..

Answer / j

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.

How is a 100 MVA transformer cooled?..

Answer / rvg

Yes there r such methods of liquid nitrogen and Hydrogen
cooling of transformer. These methods are costlier and
efficient, and requires sofisticated instruments.
This is the only method for high capacity transformers,
alternators engines etc.

How is a 100 MVA transformer cooled?..

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.
