Commissioning
SECTION 12.
DISTANCE RELAY COMMISSIONING
Please review the following important information on the GARD Distance Relay Module before
beginning the commissioning procedure.
•
If your Distance Relay module was purchased as part of the GARD8000 system, the Distance
Relay Protection Scheme logic consisting of edn, text files and Distance Relay settings were
already loaded into the GARD8000 system. However, if the Distance Relay module was added
into an existing GARD8000 system, new Distance Relay Logic and settings have to be
uploaded into the GARD8000. All the necessary steps to upload a new Distance Relay logic
are covered at the end of this Commissioning Procedure. (See Section
4.6.4.13
and 4.6.4.14).
•
Due to the large amount of Distance Relay settings and features, it is recommended that the
user obtain a copy of the GARD System Instruction Manual. A hard copy and/or a CD of the
Instruction Manual is provided with the purchased system. A software version (PDF) of the
Manual can be downloaded from RFL website at:
(
http://www.rflelect.com/operatingmanual.html
) or from the GARD8000 System chassis. Note
that because of file size restrictions the manual downloaded from the GARD chassis has all
graphics removed. (Once the GARD is powered up; from the Home web page click on
“Settings,” select “File Operations,” select “Save File to PC," select “Gard System Manual
PDF.”
•
The GARD 8000 Emulator software can be used ahead of an actual commissioning in an off-
line mode to program the Distance Relay or GARD8000 system settings and save them to a
file. Later, during the commissioning process this file can be uploaded to the GARD 8000
system. The GARD 8000 Emulator software can be downloaded from RFL website at:
http://www.rflelect.com/GARD%208000.html
•
The Distance Relay can be programmed with four independent groups of settings. Unless
specifically requested, the settings in
Group 4
are programmed with the factory default
settings. These settings can be used during the initial commissioning/startup of the GARD8000
Distance Relay system.
