•
Energy (real or imaginary) — 4 × phase CT primary setting × 1.5 × VT Secondary setting × 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.
Signal sources
Deadband parameters of measured values related to the signal sources are configured here.
Breakers
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.

XCBR1 ST.LOC OPERAND
Range: any FlexLogic operand
Default: OFF
This setting is used to select a FlexLogic operand that declares to IEC 61850 services that breaker 1 is selected for local
control. While the selected operand is asserted, Bkr0XCBR1.Loc.stVal is true and IEC 61850 commands to BkrCSWI1.Pos
and Bkr0XCBR1.Pos are not accepted, and a Negative Response (-Rsp) is issued with the REASON CODE of Blocked-by-
switching-hierarchy.
