Testing Current and Voltage Inputs

7.2.2
If you click in the project tree according to
alizing for you the current values of the measuring points existing in the device appears in an editor. On the
left side you will see the phasor diagram for 3-phase analog inputs (absolute value and phase). To the right
the measured values are displayed as numerical values. The primarily measured values for voltage and current
are shown as indicators of absolute value and phase. The reference is the voltage in phase A of measuring
point 1. If no voltage is connected, the current in phase A of measuring point 1 is the reference. All indicated
phasor values refer to the reference quantities.
You can identify and verify the following errors with measured-value control:
•
Turner in the analog wiring
•
Vector group
•
Direction between current and voltage
Devices connected via effective connections can also represent analog measuring points of remote ends as
phasors. In this case, the phasors of measuring points of up to 6 remote ends are shown. For example, the
stability of a line differential protection can thus be verified.
