WHAT IS DGA TEST FOR THE TRANSFORMERS.

Answer Posted / jadhav padmakar

DGA Means Dissolved Gas Analysis. While in service
Transformer undergoes various termal,chemical,electrical
stresses due to that some gases generated these gases known
as Fault gases which r quantitified in extremely low level
in Parts Per Million (PPM), the test which is conducted to
analyse these fault gases known as DGA Test.
