Transformer lifetime evaluation apparatus and method

A transformer lifetime evaluation apparatus using optical properties of methanol included in insulation oil, the apparatus comprising:

• a first storage part in which insulation oil used for insulating a transformer is stored;
• a second storage part which is provided separately from the first storage part and in which insulation oil not used for insulating the transformer is stored;
• a light emitting unit configured to emit a light beam having a specific wavelength;
• a light receiving unit configured to receive the light beam emitted from the light emitting unit;
• a first optical cable configured to connect the light emitting unit and the light receiving unit to provide a movement path for the light beam emitted from the light emitting unit and received by the light receiving unit and disposed to pass through the first storage part;
• a second optical cable configured to connect the light emitting unit and the light receiving unit to provide a movement path for the light beam emitted from the light emitting unit and received by the light receiving unit and disposed to pass through the second storage part;
• and
• a calculation unit connected to the light receiving unit and configured to receive information on the optical properties of the methanol from the light receiving unit.
