Patent number: 10975768Abstract: A method of preserving power quality on a power grid is provided. The method is implemented by a voltage overflow device that is electrically coupled to the power grid through electrical contacts. A voltage monitoring circuit of the voltage overflow device monitors a voltage via the electrical contacts on the power grid with respect to a predetermined voltage. The voltage monitoring circuit determines whether the voltage exceeds the predetermined voltage. A switch of the voltage overflow device shunt an excess voltage over the predetermined voltage to a resistive load when the voltage exceeds the predetermined voltage to preserve the power quality on the power grid.Type: GrantFiled: August 20, 2018Date of Patent: April 13, 2021Assignee: HAMILTON SUNSTRAND CORPORATIONInventors: Michael Krenz, Galdemir Cezar Botura
