Title: Walter A. Elmore: Innovator in Protective Relaying Systems

Introduction

Walter A. Elmore is a notable inventor based in Coral Springs, FL (US). He holds a total of 5 patents that showcase his contributions to the field of electrical engineering, particularly in protective relaying systems.

Latest Patents

One of his latest patents is titled "Drive to Last Reclosure Operation in a Protective Relaying System." This invention involves a reclosing relay that includes a reclose initiate (RI) input and a drive to last reclosure (DTLR) input. The relay provides a close signal to effect the reclosure of a circuit breaker associated with it. The relay operates upon receiving a first RI signal to provide the close signal either immediately or with a programmed time delay. It also functions with a second RI contact at its DTLR input, ensuring that the close signal is provided only after synchronism is identified between the line voltages on either side of the circuit breaker.

Another significant patent is the "Sudden Pressure Relay Supervisory Apparatus." This apparatus supervises a sudden pressure relay (SPR) system that protects a power system network transformer with multiple windings. It addresses the challenges of previous overcurrent supervision for multiple-winding transformers. The apparatus utilizes a maximum restraint signal selection network to differentiate between high and low current levels across all transformer windings. It effectively blocks the SPR from operating the breakers that isolate the transformer when the selected maximum restraint signal exceeds a predetermined level.
