发明名称 Transformer temperature monitoring and control
摘要 According to one embodiment an apparatus to monitor the temperature of a transformer is disclosed. The apparatus includes a fiber optic cable having a temperature sensing probe on one end 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. Monitors are used to monitor different parameters of the transformer. A controller generates a simulated winding temperature based on data received from the monitors and converts the electrical signal to a direct winding temperature. The controller analyzes the operation of the transformer by comparing the direct winding temperature to the simulated winding temperature. Other embodiments are disclosed herein.
