Device for reading spectral selective measuring feeder to monitor temperature of power transformer, has evaluation unit producing output signal by based on ratio of measuring values determined with operating parameter values

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention is a device that uses a light source and an evaluation unit to accurately read and monitor the temperature of a power transformer. It does so by adjusting specific operating parameters (like settings of an LED), measuring the light emitted, and calculating temperature based on the spectral characteristics of that light. The results are stored and analyzed to produce an output signal indicating the transformer's temperature.

Patent Abstract

The device has an evaluation unit (12) for adjusting an operating parameter of a light source i.e. LED (2), to different operating parameter values. The evaluation unit determines measuring values associated with the different operating parameter values, where the measuring values are dependent upon an emission spectrum of light emitted by the source. The unit comprises a storage unit (13), and the values are stored in the storage unit. An output signal (14) is produced by the unit based on a ratio of the measuring values determined with the parameter values of the source. An independent claim is also included for a method for reading a spectral selective measuring feeder.
