See the following list of supported parameters. Note that the same list is also
supported for the MSQI logical node. MSQI parameters are displayed only if the relay
supports sensitive ground CT.
GGIO3 Logical Node
Range: Enum
These are the control models supported: (0) status only, (1) direct-with-normal-
security. They can be configured under the Value column.
XCBR Logical Node
Range: the sboTimeout setting range is 500 to 60000 msec
The XCBR1 Pos sboTimeout setting is used to select SBO timeout value. To be
successful, the IEC 61850 "operate" command must be executed after the "select"
command within the XCBR1 Pos sboTimeout setting value.
XCBR-POS can be configured for status only, Direct operate, Select before operate,
Direct operate with enhanced, SBO enhanced.
Reports
The Reports tab in IEC 61580 Configurator permits configuration of data sets and report
control blocks for buffered and unbuffered reports.
To Calculate
max = (Ground CT Primary * 46)
min = 0
max = (Phase CT Primary * 46)
min = 0
max = (Sens. Ground CT Primary * 3)
min = 0
max = Aux. VT Ratio * 240
min = 0
max = (Phase CT Primary * 46)
min = 0
max = (Phase VT Ratio * 240)
min = 0
angle dB = (DB percentage* 360)
