6.2.1
Overview
The analog primary values are analog quantities measured on the primary side of the
TRM and reflect the actual current or voltage on the primary side of the VTs and CTs.
The ratio is adjusted under settings and also depends on the rating of the TRM. 24
primary values and phase angles are displayed in this view.
The analog primary values are values on the input (primary equipment side) of the
merging unit (MU). These values are scaled according to a fixed "universal" scaling of
1 mA per LSB and 10 mV per LSB and transmitted to the IED via IEC 61850-9-2 LE
protocol.
The analog primary values are values on the input (primary equipment
side) of the merging unit (MU) when IEC 61850-9-2LE process bus
communication is used. These values are scaled according to a fixed
"universal" scaling of 1 mA per LSB and 10 mV per LSB and
transmitted to the IED via IEC 61850-9-2LE protocol.
Main menu/Measurements/Analog primary values
Displays the quantities measured by the transformer module (TRM) or received via
IEC 61850-9-2 LE process bus. For each channel used the amplitude of the voltage or
current and its phase angle is shown. If the amplitude is to low for calculation, the
angle will be indicated with "- - -". The status of the module is always shown and
channels not in use are indicated with "- - " the abbreviation NC. Data from TRMs and
LDCMs as well as Merging Units can be viewed. All currents and voltages are given in
RMS values.
