The I
DENTIFIER
text field allows user to enter a single code for the circuit being defined
(maximum 15 characters). No editing allowed;
The W
IRING
scroll box allows selecting a number of elements used for measuring (1, 2,
3 or 4). No editing allowed;
Selecting the 3-
PHASE CIRCUIT SYNTHESIS
check box, the 3-phase circuit synthesis is
enabled. It is only possible to select 3-phase circuit synthesis in a 1 element circuit
(phase A, B, or C);
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 current;
The F
REQUENCY REFERENCE
scroll box allows user to select a reference voltage circuit;
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 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.
