Latest Patents
Graeme John Lloyd 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 operation. For plain (transformerless) feeders, this threshold is approximately 50%, while for transformer feeders, it is around 85% (nominally 86.7%) of the rated pre-fault load current. However, 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 operated.
