Teste Monofásico do Elemento Diferencial do SEL-787

Guia de Aplicação - Ao testar um elemento diferencial, recomenda-se usar apenas a corrente de uma fase. Embora este teste não simule condições reais de um sistema, ele fornece uma prova adequada de que o relé foi ajustado conforme desejado. Além disso, a prática do teste monofásico simplifica o teste, tornando-o adequado para todos os equipamentos de teste, uma vez que nem todos possuem seis canais de corrente para executar um teste das três fases.

Criando uma Função de Sobrecorrente com Restrição por Tensão (51V) no Relé de Proteção SEL-487E

Certas faltas fazem com que as correntes decaiam com o tempo fazendo com que a corrente falta no período de regime (“steady-state”), após alguns ciclos, possa ser menor que a corrente nominal do sistema (menor do que 1 pu). Isso significa que um relé de sobrecorrente temporizado ajustado com um valor de pickup maior do que a corrente nominal de carga para um transformador, não opere para curto-circuito em seus terminais. Antes que o relé opere, a corrente já se tornou consideravelmente menor do que o pickup do relé.

Managing IED Passwords With the SEL-3620 Ethernet Security Gateway and SEL RTAC Using SEL Server Connections

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 describes the steps to perform password management using the SEL-3620 with an RTAC set up for SEL Server Engineering Access as the intermediary device.

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.

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.

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.

Event Collection From SEL-3530 RTAC Using acSELerator Team

Application Guide - The SEL-3530 Real-Time Automation Controller (RTAC) can collect events from relays and store 512 events in its own internal, nonvolatile memory. The acSELerator Team® SEL-5045 Software can directly connect to the RTAC and collect all of these events instead of making individual connections to each relay.
