The I
NPUTS
scroll box allows user to select the inputs to which each measuring
element is connected. No editing allowed;
The N
OMINAL VALUE
text field allows user to enter a circuit rated voltage;
The R
ATIO
text fields allows user to enter ratio of power transformers for each input.
Once the circuit is created, it appears in the configuration interface menu. When
selecting the circuit, a screen shows the characteristics of the circuit selected, as
shown in Figure 22. It is possible to edit some parameters, such as nominal value and
transformation ratio.
The frequency is calculated individually for each circuit as long as the magnitude of
the voltage is over 10% of the nominal magnitude configured in the Voltage Circuit
window. The frequency track occurs within the range of Nominal Frequency ±5Hz.

4 Current Circuits
Considering the input type configurations, it is possible to create current circuits with
1, 2, 3, or 4 elements.
The phase sequences of the circuits supported by the equipment are ABC, BCA, CAB,
CBA, BAC, and CBA and may be customized by the user in the Equipment Setup,
shown in Section 2.9. The default sequence is ABC.
