1 point
a) Both for Cooling and insulation
b) Only for insulation
c) Only for Cooling
d) indication of faults​

Answer 1

hope helps

Transformer oil is used to insulate high-voltage electrical infrastructure such as transformers, capacitors, switches and circuit breakers. Transformer oils are designed to operate effectively at very high temperatures, cooling, insulating, and stopping corona discharges and arcing.

Answer 2

Answer:

Transformer oil is used in oil-filled electrical power transformers to insulate, stop arcing and corona discharge, and to dissipate the heat of the transformer (i.e. act as a coolant). Transformer oil is also used to preserve the transformer's core and windings – as these are fully immersed inside the oil.
