Patents by Inventor Frederick J. Brown

Frederick J. Brown 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).

  • Capacitive voltage transformer with improved compensating reactor arrangement
    Patent number: T966010
    Abstract: a compensating reactor in a coupling capacitor potential device including a magnetic core with an inductive winding, the reactor providing inductive reactance cancelling capacitive reactance of the device, and a voltage limiting device connected across the compensating reactor which is a ceramic oxide non linear resistor. The reactor core can be a magnetic steel whose normal saturation level substantially exceeds the voltage at which the voltage limiter changes resistance.
    Type: Grant

  • Capacitive voltage transformer with improved ferroresonance protection device
    Patent number: T967008
    Abstract: a coupling capacitor protection device with a voltage limiter connected across the tap capacitor feeding the induction transformer primary winding. The suppressor is a ceramic oxide nonlinear resistor changing from high to low resistance, thereby limiting the tap voltage to less than that at which the induction transformer core saturates in order to minimize ferroresonance in the circuit. Also, the limiter gives voltage protection to the tap capacitor circuit.
