6-12 D30 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUALMETERING CHAPTER 6: ACTUAL VALUES6This status is relevant to R-GOOSE reception when configured for SSM or ASM reception modes. It is not relevant for GOOSEor for R-GOOSE in unicast reception mode.ARP — The unicast mode of R-GOOSE transmission requires Address Resolution Protocol (ARP) for the resolution of thenetwork layer address into the MAC layer address. R-TxGOOSE## ARP status On indicates that ARP responses are beingreceived and the destination MAC address for R-GOOSE transmissions has been obtained. This status remains Off ifTxGOOSE## is not configured for R-GOOSE. It also remains Off if setting R-TxGOOSE1 DST IP is set to a multicast address. Inthe case where setting R-TxGOOSE1 DST IP is configured with a unicast address and this status indicates Off, TxGOOSE##transmission will be off, and therefore communication network diagnosis needs to be carried out.This status is only applicable for R-GOOSE transmission with setting R-TxGOOSE1 DST IP set to a unicast IP address. It is notapplicable for GOOSE or for R-GOOSE when setting R-TxGOOSE1 DST IP is multicast.6.4 Metering6.4.1 Metering conventions6.4.1.1 UR convention for measuring powerThe figure illustrates the conventions established for use in UR devices.
