Applying the SEL-411L
Relays
When applying the SEL-411L Relay in line current differential applications,
relays at all terminals of a protected line must use firmware that is compatible,
as shown in Table A.2.
➤ Fixed line current measurement when using different CTR settings.
➤ Corrected the SALARM bit during Access Level change.
➤ Added Relay Word bit 87LSP to indicate 87L spurious pickup.
➤ Changed the default setting of 87CHTRG to 87LSP.
➤ Changed the default setting of 87LPP to 1.2.
➤ Reduced maximum event report length and total event storage.
➤ Improved power factor measurements.
➤ Increased number and type of power system components for
Bay Control screens.
➤ Fixed UTC time offset on Synchrophasor recording files.
➤ Corrected 87TAPCC setting range in 1 A Relay.
➤ Corrected V1 calculation in three-pole applications.
➤ Improved synchrophasors functionality.
➤ Fixed initialized logic values in 61850 MMS.
➤ Improved disconnect switch logic.
➤ Improved dual breaker applications by allowing different CT
ratios for all functions.
➤ Enhanced accuracy of relay timekeeping system; SNTP no
longer meets high-accuracy requirements.
➤ Added the ability to receive high-accuracy IRIG from the serial port.
➤ Expanded list of analog quantities and Relay Word bits.
➤ Added restraint currents and Alpha Plane values to default event
report.
➤ Corrected displayed values in event report when 87L is not enabled.
➤ Reduced DNP current zeroing from 5% to 0.5%.
➤ Fixed possible buffer overflow when using SEL protocol.
➤ Added code to restart the relay in case of FPGA FAILURE.

SEL-411L-1-R105-V0-Z002001-D20120228
➤ Improved Ethernet communications when using UDP.
➤ Improved Alpha Plane ratio metering.
➤ Fixed issue when using differential current as a time-overcurrent
operating quantity.
➤ Corrected fault location display when event is triggered by ER.
➤ Fixed Fast Message time-stamp offset.
➤ Enhanced 87L fault selection logic for single-pole trip applications.
➤ Added Relay Word bit 87FIDEN.
