ACTUAL VALUES  METERING  RxGOOSE Analogs
 RxGOOSE
 Analogs
The D30 is provided with optional GOOSE communications capability. This feature is specified as a
software option at the time of ordering. See the Order Codes section of chapter 2 for details.
The RxGOOSE Analog values display in this menu. The RxGOOSE Analog values are received via IEC 61850 GOOSE
messages sent from other devices.

BASE = 2000 kA × cycle
BASE = maximum value of the DCMA INPUT MAX setting for the two transducers configured
under the +IN and –IN inputs.
BASE = Line Length as specified in Fault Report
f = 1 Hz
BASE
ϕ = 360 degrees (see the UR angle referencing convention)
BASE
PF = 1.00
BASE
BASE = 100°C
I = maximum nominal primary RMS value of the +IN and –IN inputs
BASE
P = maximum value of V
BASE BASE
V = maximum nominal primary RMS value of the +IN and –IN inputs
BASE
V = maximum primary RMS value of all the sources related to the +IN and –IN inputs
BASE
Z = PhaseVTSecondary / PhaseCTSecondary, where PhaseVTSecondary and
BASE
PhaseCTSecondary are the secondary nominal voltage and the secondary nominal current of the
distance source. In case multiple CT inputs are summed as one source current and mapped as the
distance source, use the PhaseCTSecondary value from the CT with the highest primary nominal
current.
Distance source is specified in setting under SETTINGS  GROUPED ELEMENTS  SETTING
