Latest Patents
One of Vijay Shah's latest patents is titled "Integration and compensation for a protection relay." This invention relates to a method of integration and compensation in a protection relay. The method includes the protection relay receiving a measured signal from a Rogowski coil and converting the measured signal to digitized samples. The measured signal is a differentiated current signal over time. The process involves iteratively computing integrated current data from the digitized samples using a first digitized function to obtain an integrated value. Additionally, it includes iteratively computing compensated current data from the integrated current data using a second digitized function to remove a DC component in the integrated current data. The compensated current data is then evaluated to identify a fault condition, generating a trip signal upon identification of a fault to operate a switch that electrically disconnects to protect the power equipment. The steps of integration and compensation are performed within the time period of the measured signal.
Another notable patent is the "Human-machine interface for a self-supplied relay." This design focuses on a protection relay
