RP1 operation signal can befound at signal monitoring point ’RP1R’ during that time.Note: RP1 operation will be canceled by undervoltage (RP-UVBLK) and undercurrent(RP-UCBLK) elements, when the input signals are not obtained sufficiently (i.e.,Ve and Ie are less than 0.5V and 0.001A). For more information, see ChapterTechnical description: Transformer module for AC analog input (→p. 627).The RP element will be characterized by Watt metric setting; hence, a value, which is ruled bythe scalar product of an entering current (Ie) and applied voltage (Ve), should be set for thesetting [RP1].2.4.7 Setting of standby earth-faultIn which case the residual current is injected from the neutral circuit at the lower side of atransformer, the standby earth-fault protection can trip the CB located at the lower side of thetransformer; the trip command is issued by the SEF1 element, but issuing is retarded bysetting [TSEF1S2] compared with the original SEF1 issuing. The user should set On for thescheme switch [SEF1S2-EN]†.†Note:The standby earth-fault protection is only available for the SEF1 element.2.4.8 Scheme logicThe scheme logic for both the non-directional and the directional SEF1 element is illustrated
