Title: Innovations of Charles A. Crotty
Introduction
Charles A. Crotty is an accomplished inventor based in Harwinton, Connecticut. He holds two patents that showcase his expertise in electrical engineering and innovation. His work has significantly contributed to advancements in line voltage monitoring systems.
Latest Patents
One of Crotty's latest patents is the Line Voltage Monitor System. This innovative system derives a synchronization signal from the half-wave crossovers of the AC power line. It features a half-wave peak detector that identifies the peak voltage of each half wave. Additionally, an impulse detector captures any voltage impulses occurring during a half-wave. A common mode detector measures the peak value across the common mode terminals. The system is equipped with a microcomputer and a clock/calendar to record threshold values and monitor for any detected SAG or SURGE events. It meticulously logs the time of initiation, the voltage of the most significant SAG or SURGE, and the number of cycles involved. The system also tracks the average peak values over the last thirty-two half cycles to determine if an event has occurred. If an event is detected, it records the duration and the lowest average during the event. Furthermore, it captures the timing of impulses and the peak voltage during the half cycle of the event. The system also logs blackout times, providing comprehensive monitoring capabilities.
