5-64 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUALPRODUCT SETUP CHAPTER 5: SETTINGS5Figure 5-22: Deadband settingsDeadband settings are entered in UR Setup in units of percent of the difference between the "max." and "min." of theassociated analog value. A zero deadband setting suppresses transmission triggering. The range of deadband settings is0.000 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 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.Breaker 1The 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.
