IEC05000465 V2 EN-USFigure 96: Typical connection for STBPTOC in 1½-breaker arrangement.8.7.3 Setting guidelines M12909-3 v5The parameters for Stub protection STBPTOC are set via the local HMI or PCM600.The following settings can be done for the stub protection.GlobalBaseSel: Selects the global base value group used by the function to define (IBase),(UBase) and (SBase).Operation:Off/OnReleaseMode: This parameter can be setRelease orContinuous. With theRelease setting thefunction is only active when a binary release signal RELEASE into the function is activated. Thissignal is normally taken from an auxiliary contact (normally closed) of the line disconnectorand connected to a binary input RELEASE of the IED. With the settingContinuous the functionis activated independent of presence of any external release signal.I>: Current level for the Stub protection, set in % ofIBase. This parameter should be set so thatall faults on the stub can be detected. The setting should thus be based on fault calculations.t: Time delay of the operation. Normally the function shall be instantaneous.8.8 Pole discordance protection CCPDSC IP14516-1 v51MRK 505 363-UEN A Section 8Current protection167Application manual
