Application Guide - Using acSELerator Quickset to load settings into an SEL-351S relay is typically a straightforward process with few problems provided the relay model number and setting version number match the relay being placed into service.

This application guide provides recommended practices for commissioning an SEL Integrated Communications Optical Network (ICON) SONET or virtual synchronous network (VSN).

This application guide discusses how to configure the RTAC in a typical SCADA application. This example show an RTAC polling an SEL relay with SEL Fast Message protocol and the RTAC being polled by a SCADA master using DNP3 serial protocol.

SEL ICON supports a four-port E1 Sync Submodule (8057-15). This application guide provides instructions for setting up the E1 Sync Submodule to perform E1 channel bank functionality using E0 hairpinning of circuit data from supported low-speed TDM interfa
