SECTION 1
Introduction
The SEL-400 series family of relays feature high-performance protection for a
variety of applications. All relays feature extensive metering, monitoring, and
data recording, including high-resolution data capture and reporting.
Relays feature expanded SEL
OGIC control equation programming for easy and
flexible implementation of custom protection and control schemes. The relays
have separate protection and automation SEL
OGIC control equation programming
areas with extensive protection and automation programming capability.
Relays provide extensive communications interfaces from standard SEL ASCII
and enhanced M
IRRORED BITS communications protocols to Ethernet connectiv-
ity with the optional Ethernet card. With the Ethernet card, you can employ com-
mon industry communications tools, including Telnet, FTP, DNP3 (serial and
LAN/WAN), and the IEC 61850 Edition 2 standard suite of protocols.
Relays interface with
ACSELERATOR QuickSet SEL-5030 Software. QuickSet
assists you in setting, controlling, and acquiring data from the relays, both locally
and remotely.
ACSELERATOR Architect SEL-5032 Software is included with pur-
chase of the optional Ethernet card with IEC 61850 protocol support. Architect
enables you to view and configure IEC 61850 settings via a GUI.
Most relays support synchrophasor measurement. Synchrophasor measurements
are available when a high-accuracy time source is connected to the relay. The
relay supports the IEEE C37.118, Standard for Synchrophasors for Power Sys-
tems.
Most relays feature bay control functionality. The mimic display selected is dis-
played on the front-panel screen in one-line diagram format. The number of dis-
connects and breakers that can be controlled by the relay are a function of the
selected mimic display screen. Control of the breakers and disconnects is avail-
able through front-panel pushbuttons, ASCII interface, Fast Message protocol, or
SEL
OGIC control equations.
A simple and robust hardware design features efficient digital signal processing.
Combined with extensive self-testing, these features provide relay reliability and
enhance relay availability.
Common Features
Automation. Take advantage of enhanced automation features that include
programmable elements for local control, remote control, protection
latching, and automation latching. Local metering on the large-format
front-panel LCD eliminates the need for separate panel meters. Use serial
and Ethernet links to efficiently transmit key information, including
metering data, protection element and control I/O status, Sequential
Events Recorder (SER) reports, breaker monitor, relay summary event
reports, and time synchronization. Use expanded SEL
OGIC control equa-
NOTE: Some SEL-400 series devices
are compliant with Edition 1 of the
IEC 61850 standard.
