Firmware and Manual Versions
Firmware
➤ Increased the number of Goose subscriptions to 128.
➤ Added new Logical Nodes RDRE and RFLO for MMS File
Services.
➤ Updated Traveling Wave COMTRADE reports to contain six
analog channels and no digital channels.
➤ Corrected Alpha Plane labels in EVE Command.
➤ Corrected an issue with the High-Speed Enable setting that was
incorrectly set during a firmware upgrade.
➤ Added traveling wave peak arrival time estimates to DNP.
SEL-411L-R110-V0-Z005002-D20130621
SEL-411L-1-R110-V0-Z005002-D20130621
➤ Manual Update only (see Table A.5) 20130821
SEL-411L-R110-V0-Z005002-D20130621
SEL-411L-1-R110-V0-Z005002-D20130621
➤ Increased the pickup timer for the dSCV1_S comparison logic
in the relay three-phase fault detector (DTF logic) to 20 cycles
to ensure proper operation during very slow power swings.
➤ Improved the accuracy of year rollover for non-leap years when
relay is using IRIG signal without control bits.
➤ Added a VMEMC setting which selects between short or
medium length memory voltage as the polarizing quantity in
distance calculations. The relay uses the medium-length
memory when ESERCMP = Y to ensure proper operation
during voltage inversions. This addresses an issue with firmware
revision R108 for system faults that cause voltage inversions on
series-compensated lines.
20130621
➤ Corrected an issue where an SEL-2600 RTD module and
2800M transceiver could not communicate with an SEL-411L.
This defect only affects firmware R108.
➤ Added support for third I/O board.
➤ Added a setting to disable background ASCII communications
over 87L link.
SEL-411L-R109-V0-Z004002-D20130401
SEL-411L-1-R109-V0-Z004002-D20130401
➤ Not for public release. 20130401
SEL-411L-R108-V0-Z003002-D20121005
SEL-411L-1-R108-V0-Z003002-D20121005
➤ Manual Update only (see Table A.5) 20130311
SEL-411L-R108-V0-Z003002-D20121005
SEL-411L-1-R108-V0-Z003002-D20121005
➤ Changed default Group Setting ARESE from Y to N .
➤ Reduced the normal time constant of the distance element
polarizing voltage memory to more closely follow changes in
power system frequency; the time constant automatically adapts
to provide security for zero-voltage three-phase faults.
➤ Added traveling wave fault location to SEL-411L-1.
➤ Added traveling wave COMTRADE events to SEL-411L-1.
➤ Corrected ground directional performance when switching
between elements.
➤ Made Relay Word bits 87ERR1 and 87ERR2 visible in Access
Level 2.
➤ Added the COM 87L WD C command to reset watchdog
counters that produce 87ERR1 and 87ERR2 alarm bits.
➤ Improved performance of external fault detection logic.
➤ Added Relay Word bits IWDD, IXDD, VYDD, VZDD, 87DDIL,
87DDVL, and 87DDRD to disturbance detection logic.
➤ Improved 87L resampling to reduce operate time.
