Using an RTAC to Monitor GOOSE Statistics on SEL Relays

GOOSE message statistics provide important insight into the health of a network and devices that handle GOOSE message publishing, delivery, and consumption. Adding flex parse messages to an RTAC on a network provides an easy way to monitor and report changes to GOOSE statistics of connected SEL relays. Early detection of delayed or lost messages can prevent undesirable operation or missed trip scenarios in protection and automation schemes that rely on timely GOOSE messaging.

Whitelist Antivirus Using McAfee Embedded Control

McAfee Embedded Control is a useful security tool for embedded computers with limited CPU and memory resources. It is also useful for computers that do not have access to continuous software updates. Its primary protection mechanism is a process called whitelisting, which limits the execution of software on a computer to a set of trusted applications. In addition to whitelisting, it also provides memory and file system protection. This application guide summarizes how many of the McAfee Embedded Control features work so that the user can make informed decisions when evaluating, setting up, or fine-tuning an installation. It also provides basic guidelines for installation, monitoring, and troubleshooting.

Managing IED Passwords Over SEL Protocol With the SEL-3620 Ethernet Security Gateway and SEL-3530 RTAC

When the SEL-3530 RTAC uses SEL Protocol to poll an SEL device, it must have knowledge of the ACC (and sometimes 2AC) level password of the “child” relay to perform event retrieval, fast breaker, and other command operations. If the SEL-3620 performs a password update on the SEL device, the SEL-3620 must update the RTAC internal database with the child’s new ACC and 2AC passwords or risk the RTAC losing operational visibility on the child relay. This application guide focuses on developing the necessary logic to solve the problem.

Single-Phase Testing of the SEL-787 Differential Element

Application Guide - When testing a differential element, it is desirable to only use current on a single phase. Although this does not simulate actual conditions on a system, it does provide adequate proof that the relay has been set as desired. In addition, single-phase testing simplifies the test and makes it suitable for all test sets because not all test sets have six current channels to drive a three-phase test.

A common application of transformer differential relays is the protection of a delta-wye power transformer. The current entering the primary side of the transformer is compared to the current leaving the secondary side. The transformer causes a phase shift between the primary and secondary currents, which must be accounted for in the relay settings. The purpose of this application guide is to develop an understanding of the phase shift and explain how to derive it for any installation. This application guide provides general information on deriving the phase shift, followed by a detailed example.

This application guide provides detailed information on how to implement the SEL IDS along with traditional protection elements using the SEL-751A.

A Zone-Switching Application for the SEL-487B Relay

Application Guide - The SEL-487B Bus Differential and Breaker Failure Relay provides differential protection for as many as six single-phase zones and includes circuit breaker failure protection for up to six three-phase circuit breakers. Advanced zone selection logic in the SEL-487B uses disconnect auxiliary contacts to automatically reconfigure bus protection zones during disconnect switch operation. This application guide discusses how to configure the SEL-487B for a simple zone-switching bus differential application in a basic two-bus station.

Enabling Sensitive Directional Tripping for Non-Line Protection Applications With SEL-351 Series Relays

It is common to enable a sensitive, directionally supervised phase overcurrent element for nonline protection applications, such as on the low-voltage side of a dual-sourced transformer. Great care must be taken when setting SEL-351 series relays in these non-line protection applications in order to maintain security and still provide the intended sensitive operation. This application guide discusses the settings required to establish the desired security and sensitivity.

Effect of Zone 3 Settings on Fault Type Selection in SEL-121F, SEL-121S, SEL-121-0, SEL-221F, SEL-221S, and SEL-221-16 Relays

Application guide -  The SEL-121F, SEL-121S, SEL-121-0, SEL-221F, SEL-221S, and SEL-221-16 Relays were designed in the 1980s and include phase and ground distance elements. There is not enough processing power in an eight-bit microcontroller to check all of the distance elements (AB, BC, CA, AG, BG, and CG) for each zone during every one-quarter-cycle processing interval. Therefore, these relays use a method for faulted phase identification that is described in this application guide.

Create a Synchrophasor Network With the SEL-3378 Synchrophasor Vector Processor

Using the SEL-3378 Synchrophasor Vector Processor (SVP), you can create a synchrophasorbased measurement network with any relay capable of performing synchrophasor measurements. This application guide details the hardware, connections, and device settings of such a network using an SEL-421 Protection, Automation, and Control System and an SEL-351S Protection System (not the Legacy SEL-351S Protection and Breaker Control Relay), because these products are among the more commonly used SEL relays. You may also apply this guide to the setup of other relays that support IEEE C37.118.
