Selectivity, also known as circuit breaker discrimination, is the coordination of overcurrent protection devices so that a fault in the installation is cleared by the protection device located immediately upstream of the fault. The purpose of selectivity is to minimize the impact of a failure on the network.
The National Public Warning System, also known as the Primary Entry Point (PEP) stations, is a network of 77 radio stations that are, in coordination with FEMA, used to originate emergency alert and warning information to the public before, during, and after incidents and disasters. PEP stations are equipped with additional and backup ...
The schematic diagrams for relay logic circuits are often called line diagrams, because the inputs and outputs are essentially drawn in a series of lines. A relay logic circuit is an electrical network consisting of lines, or rungs, in which each line or rung must have continuity to enable the output device. A typical circuit consists of a ...
The goal is to minimize an outage to the greatest extent possible. Historically, protective device coordination was done on translucent log–log paper. Modern methods normally include detailed computer based analysis and reporting. Protection coordination is also handled through dividing the power system into protective zones.

Shuttle hurdle relay (SHR) is a type of a relay race in track and field in which participants jump (sprint) over hurdles.The shuttle hurdle relay is contested at the Drake Relays, Desert Conference Relays, [1] Kansas Relays, Mt. SAC Relays, Penn Relays, Texas Relays, Akron Relays, Alabama Relay, Appalachian Conference Relay, Florida Relays (Gainesville), Knoxville Relay, Long Beach Relay, Ohio ...
The relay analyzes the resultant A/D converter outputs to determine if action is required under its protection algorithm(s). Protection algorithms are a set of logic equations in part designed by the protection engineer, and in part designed by the relay manufacturer. The relay is capable of applying advanced logic.
