(maximum 15 characters). No editing allowed;
The W scroll box allows selecting a number of elements used for measuring (1, 2,

enabled. It is only possible to select 3-phase circuit synthesis in a 1 element circuit
(phase A, B, or C);
The I scroll box allows user to select the inputs to which each measuring
NPUTS
element is connected. No editing allowed;
The N text field allows user to enter a circuit rated current;

.
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 23. It is possible to edit some parameters, such as nominal value,
frequency reference, and transformation ratio.
The frequency is calculated individually for each circuit as long as the magnitude of
the current is over 10% of the nominal magnitude configured in the Current window
of the chosen Voltage Circuit. The frequency track occurs within the range of
Nominal Frequency ±5Hz.
