According to one embodiment an apparatus to monitor the temperature of a transformer is disclosed. The apparatus includes a bundled fiber optic cable having a temperature sensing probe on one end. The probe is embedded in windings of a transformer. An optical converter transmits light to the probe and receives light from the probe, and converts the light received to an electrical signal. The light received back from the probe is controlled by temperature of the probe. A controller converts the electrical signal into a temperature. Other embodiments are disclosed herein.
