CHAPTER 5: SETTINGS PRODUCT SETUPB30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL 5-895• 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 degreesSelect the deadband settings from knowledge of the characteristics of the power system quantity measured andknowledge of the demands of the applications receiving the measurement via GOOSE or report such that changes ofsignificance to the application are promptly reported, yet the network is not overly burdened with event messages.Signal sourcesDeadband parameters of measured values related to the signal sources are configured here.BreakersThe UR breaker control and status monitoring elements have certain settings that configure how the IEC 61850 protocolinteracts with these elements. These settings are described in this section. See the Breakers section in the System Setupsection 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 thatconfigure the IEC 61850 protocol interface with the first breaker control and status monitoring element. The settings andfunctionality for the others are similar.Figure 5-40: IEC 61850 Breaker panelXCBR1 ST.LOC OPERANDRange: any FlexLogic operandDefault: OFFThis setting is used to select a FlexLogic operand that declares to IEC 61850 services that breaker 1 is selected for localcontrol. While the selected operand is asserted, Bkr0XCBR1.Loc.stVal is true and IEC 61850 commands to BkrCSWI1.Posand Bkr0XCBR1.Pos are not accepted, and a Negative Response (-Rsp) is issued with the REASON CODE of Blocked-by-switching-hierarchy.
