transformer that you will normally find defined as “220 KV/110 V”.
You must divide both the primary and secondary values by the
square root of 3, to find the values of Phase Voltage to Neutral.
You can enter different values for the sources (Vs) from 1 to 3 and for sources
(Vs) from 1 to 6.
IMPORTANT:
You must enter the data corresponding to Current in the following
way:
In the window corresponding to “Primary Rated Intensity” you must
enter the rated value of the transformer primary in
Amps
(e.g. 2000
A) and in the window corresponding to “Secondary Rated Intensity”
you must enter the rated value of the transformer secondary in
Amps
(e.g.: 5 A).
You can enter different values for the sources (Cs) from 1 to 3 and for
sources (Cs) from 1 to 6. Sources 7 to 9 and 10 to 12 refer to the voltage
channels in current mode.
•
Default values:
Enter the voltage value in volts that you want to have as
default value in the window marked “Voltage”, by pressing on it.
•
In the window marked “current” the current value in amps that you wish to
have as default value by pressing on it.
•
Degree scale:
This refers to the way the phase angle of each source is
viewed and selected. Depending on the operator’s preferences you can select
between a scale of 0 to 360º and a scale from +180º to -180º. To do this,
press on the desired option.
•
Direction of rotation:
This refers to the agreement adopted to define which
is the direction of rotation of positive angles, as shown on the displays of the
source control This can be selected as clockwise (to the right), or anti-
clockwise (to the left). Press on the desired option to select.
