Title: Joseph J DeRosa, Jr: Innovator in Generator Protection Systems
Introduction
Joseph J DeRosa, Jr. is a notable inventor based in Trumbull, CT (US). He has made significant contributions to the field of electrical engineering, particularly in the area of protection systems for AC generators. With a total of 2 patents to his name, DeRosa's work has had a meaningful impact on the reliability and safety of diesel-engine generator sets.
Latest Patents
One of DeRosa's latest patents is a protection system for AC generators. This innovative circuit is designed to protect the AC generator and/or load of a diesel-engine generator set. The system includes a circuit that measures the current in each phase of the AC generator. It features a switching circuit that activates protection if the current in any phase exceeds a predetermined threshold for a specified duration. For diesel-engine generator sets generating three-phase 460 V at up to thirty amperes continuously, the preferred overcurrent threshold is thirty-five amperes, with a time allowance of five seconds to accommodate inrush currents. The circuit also ensures that the current in any phase remains below fifty percent of the average current across all three phases. If an imbalance or overcurrent is detected, the circuit can short circuit the field winding of the AC generator, effectively shutting it down, and can also close a fuel valve to turn off the engine.
Career Highlights
Joseph J DeRosa, Jr. is currently employed at B. A. Bodenheimer and Co., Inc. His work at this company has allowed him to further develop his expertise in electrical systems and contribute to innovative solutions in generator protection.
