Patents by Inventor Fritz Weiler

Fritz Weiler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • High voltage power transformer winding temperature control system
    Patent number: 4258570
    Abstract: A winding temperature heater well for detecting the temperature of the oil about the coils in large transformers. The heater well comprising a temperature detecting device enveloped by a grid-patterned resistor element, the current through which varies directly with the current through the transformer, and a sleeve which protects the resistor and temperature detecting device from the oil. The heater well is embedded in a resin plate in such a manner as to allow calibration of the resistor from outside the plate.
    Type: Grant
