SEL-411L Relay Protection Manual Date Code 20151029
Introduction and Specifications
Features
The relay includes the ACSELERATOR QuickSet
®
SEL-5030 Software
program.
ACSELERATOR QuickSet assists you in setting, controlling, and
acquiring data from the relays, both locally and remotely.
ACSELERATOR
Architect
®
Software is included with purchase of the optional Ethernet card
with IEC 61850 protocol support.
ACSELERATOR Architect enables you to
view and configure IEC 61850 settings via a GUI interface.
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 Systems.
The relay features bay control functionality. The mimic display selected is
displayed on the front-panel screen in one-line diagram format. The number
of disconnects 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 available through front-panel pushbuttons, ASCII interface, Fast Message,
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.
