CHAPTER 5: SETTINGS
Deadband settings are entered in UR Setup in units of percent of the difference between the "max." and "min." of the
associated analog value. A zero deadband setting suppresses transmission triggering. The range of deadband settings is
0.000 to 100.000% in steps of 0.001. The default value is 10.000%.
GGIO4 elements have individual settings for "min." and "max." The min. and max. for FlxEIGAPC#.OpSig.db (FLEXELEMENT #
OpSig) are -50 pu and +50 pu respectively. The min. value for all other quantities is 0. The max. values are as follows:
• Phase current — 46 x phase CT primary setting
• Neutral current — 46 x ground CT primary setting
• Phase and phase-to-phase voltage — 275 x VT ratio setting
• Power (real, reactive, apparent, 3-phase, and 1-phase) — 46 x phase CT primary setting x 275 x VT ratio setting
• Energy (real or imaginary) — 46 x phase CT primary setting x 275 x VT ratio setting x 1 hour
• Frequency — 90 Hz
• Frequency rate of change — 90 Hz/s
• Power factor — 2
• Angle — 360 degrees
Select the deadband settings from knowledge of the characteristics of the power system quantity measured and
knowledge of the demands of the applications receiving the measurement via GOOSE or report such that changes of
significance to the application are promptly reported, yet the network is not overly burdened with event messages.
Breaker 1
The UR breaker control and status monitoring elements have certain settings that configure how the IEC 61850 protocol
interacts with these elements. These settings are described in this section. See the Breakers section in the System Setup
section of this chapter for details on the operation of breaker control elements.
Navigate to Settings > Communications > IEC 61850 > System Setup > Breakers > Breaker 1 to access the settings that
configure the IEC 61850 protocol interface with the first breaker control and status monitoring element. The settings and
functionality for the others are similar.
