6.3.16 TxGOOSE status

ACTUAL VALUES  STATUS  TxGOOSE STATUS
 TxGOOSE STATUS

The B90 is provided with optional IEC 61850 capability. This feature is specified as a software option at the time
of ordering. See the Order Codes section of chapter 2 for details.
This status is relevant to R-GOOSE reception when configured for SSM or ASM reception modes. It is not relevant for GOOSE
or for R-GOOSE in unicast reception mode.
— The unicast mode of R-GOOSE transmission requires Address Resolution Protocol (ARP) for the resolution of the
ARP
network layer address into the MAC layer address. R-TxGOOSE## ARP status On indicates that ARP responses are being
received and the destination MAC address for R-GOOSE transmissions has been obtained. This status remains Off if
TxGOOSE## is not configured for R-GOOSE. It also remains Off if setting R-TxGOOSE1 DST IP is set to a multicast address. In
the 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 not
applicable for GOOSE or for R-GOOSE when setting R-TxGOOSE1 DST IP is multicast.

6.4 Metering

6.4.1 Metering conventions

6.4.1.1 UR convention for measuring phase angles
All phasors calculated by URs and used for protection, control and metering functions are rotating phasors that maintain
the correct phase angle relationships with each other at all times.
For display and oscillography purposes, all phasor angles in a given relay are referred to an AC input channel pre-selected
by the
SETTINGS  SYSTEM SETUP  POWER SYSTEM  FREQUENCY AND PHASE REFERENCE
particular AC signal source to be used as the reference.
If the AC signal pre-selected by the relay upon configuration is not measurable, the phase angles are not referenced. The
phase angles are assigned as positive in the leading direction, and are presented as negative in the lagging direction, to
more closely align with power system metering conventions. The figure illustrates this.
