Title: The Innovations of Jay K Marshall
Introduction
Jay K Marshall is a notable inventor based in Marietta, GA (US). He has made significant contributions to the field of electrical engineering, particularly in power measurement systems. With a total of 3 patents, his work has had a considerable impact on energy consumption monitoring.
Latest Patents
One of his latest patents is focused on power measurement in an electrical distribution system having three or more wires. This innovative system utilizes a Hall-effect generator directly coupled to one of the live wires of the circuit, along with current transformers linked to the other live wires. The output from each current transformer is magnetically connected to the Hall-effect generator, which produces an output proportional to the vector sums of the currents and the potential between the live wires. This output can be accumulated to indicate the energy consumed by a load connected to the live wires. Additionally, a high-frequency A.C. bias is applied to linearize the output of the generator.
Another significant patent is for a gain switching device with reduced error for watt meters. This apparatus is designed to control a signal through a switching function that is a function of the signal itself. It includes a circuit that minimizes errors caused by common frequency components in both the switching function and the signal being switched. By eliminating the common frequency component and replacing it with a component at a multiple frequency, the device effectively reduces DC error.
