The Radiators are used in transformer for

A. accelerates the cooling rate of the transformer
B. Breathing process
C. Reduced Voltage Level 
D. None of the Above 

Answer 
A. accelerates the cooling rate of the transformer

Explanation :
  • When a transformer is loaded, the current starts flowing through its windings. Due to this flowing of electric current, heat is produced in the windings, this heat ultimately rises the temperature of transformer oil. 
  • We know that the rating of any electrical equipment depends upon its allowable temperature rise limit. Hence, if the temperature rise of the transformer insulating oil is controlled, the capacity or rating of the transformer can be extended up to a significant range. 
  • The radiator of the transformer accelerates the cooling rate of the transformer. 
  • Thus, it plays a vital role in increasing the loading capacity of an electrical transformer. This is the basic function of a radiator of a power transformer.
