Title: John William Wright: Innovator in Overcurrent Protection Technology
Introduction
John William Wright is a notable inventor based in Stoke-on-Trent, GB. He has made significant contributions to the field of electrical engineering, particularly in the area of overcurrent protection systems. His innovative approach has led to the development of a unique patent that addresses critical challenges in electrical safety.
Latest Patents
Wright holds a patent for a device titled "Parallel-feeder directional overcurrent protection." This invention focuses on the inclusion of directional overcurrent protection relays at the load end of parallel feeders fed from an AC power source. The patent specifies a minimum fault-current threshold based on the potential of a phase-to-phase fault at the source, which can mislead relay operations. For plain (transformerless) feeders, this threshold is approximately 50% of the rated pre-fault load current, while for transformer feeders, it is around 85% (nominally 86.7%). Notably, these thresholds can be disregarded if the relay outputs are processed in a 2-out-of-3 circuit, ensuring that a relay on one phase will only operate its associated circuit breaker if another phase's relay has also activated.
Career Highlights
Wright is currently employed at Alstom UK Limited, where he continues to apply his expertise in electrical engineering. His work at Alstom has allowed him to collaborate with other talented professionals in the field, enhancing the development of innovative solutions for electrical systems.
