Patents by Inventor Sai Pawan Kumar Chevuru

Sai Pawan Kumar Chevuru 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).

  • System and method for protection of electrical appliances
    Patent number: 8659865
    Abstract: An electrical circuit for protecting an electrical load from overload current is provided. The system includes a voltage transformer configured to receive AC mains voltage from an electric mains supply and further configured to apply reduced voltage to the electrical load. A control switch comprising metal contacts is connected to the voltage transformer. The control switch is configured to facilitate application of reduced value of AC mains voltage to the electrical load. A reduced value of current flowing through the electrical load is measured by a current transformer connected in series with the electrical load. The reduced value of current is then used for estimating a current consumption value in event of AC mains voltage being directly applied to the electrical load. A control signal is then used for disconnecting the electrical circuit if the estimated current consumption value is greater than threshold overload current value.
