6.2 View analog primary values
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) 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 "- - " . Data from TRMs and LDCMs as
well as Merging Units can be viewed. All currents and voltages are given in RMS
values.
6.3 View analog secondary values
6.3.1 Overview
Analog secondary values shows secondary CT currents and VT voltages. These are
the actual current and voltage values at the TRM inputs.
For analog values received from Merging Units, no analog secondary values are
shown.
Main menu/Measurements/Analog secondary values
Displays up to 24 channels with secondary CT and VT data. RMS values are shown.
