Title: Innovations by John J Shea

Introduction

John J Shea is a notable inventor based in Wake Forest, NC (US). He holds 4 patents that showcase his contributions to electrical safety and power management systems. His work is particularly significant in the realm of fault management and arc flash detection.

Latest Patents

One of Shea's latest patents is the Fault Managed Power System (FMPS). This system monitors and detects fault currents in Power over Ethernet (PoE), Power Factor Correction (PFC), and other cables. It is designed to limit energy levels to prevent human contact from causing ventricular fibrillation, thereby ensuring a touch-safe environment. The system automatically removes power from cables during overload or short-circuit conditions, which helps prevent electrical fires and protects system components. This innovative approach allows for increased power levels in applications like PoE and PFC, exceeding the current maximum of 100 W.

Another significant patent by Shea is the Arc Flash Detection Method. This method involves monitoring near-field and far-field radio frequency (RF) signals around circuit breaker contacts. By analyzing these signals along with the rate of change of current, the system can detect arc faults and implement a tripping operation to disconnect the power supply. This invention enhances safety by preventing potential electrical hazards.
