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.
Main menu/Measurements/Analog primary values
Displays the quantities measured by the transformer module (TRM). 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 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.
Main menu/Measurements/Analog secondary values
Displays up to 24 channels with secondary CT and VT data. RMS values are shown.
6.4 View analog mean values
6.4.1 Overview
Measurements from the Milliampere Input Module (MIM) are found in this part of
the measurements menu. Data from either the hard wired mA module or Signal
Matrix Tool mA modules are shown here.
