Abstract
A thermometer formed wholly of dielectric components inserted between the coils of a transformer winding immersed in cooling fluid within the case of a high voltage transformer, the thermometer having a rod responsive to temperature changes within the case to vary light transmission across terminals of a pair of fiber optics to an external signal converter connected to transmit converted signals to a readout unit. The body of the thermometer may take various forms according to the applications intended. In applications not requiring dielectric components, the body and sensing rod may each be formed of a different metal, with that of the body having a lower coefficient of thermal expansion than that of the other.
