From the
Device Front
With a device ready for operation, first press the
key. The
0$,10(18
appears.
Use the
key to select the menu item
0HDVXUHPHQW
, and switch to the list of mea-
sured values using the
key. The
0($685(0(17
selection appears. See figure 7-

Figure 7-20 Selection of Measured Values in the HMI — Example
The measured values are divided into the following groups:
1.
2SHUDWLRQSUL
Operating measured values, primary.
The measured values are converted from secondary to pri-
mary according to the settings entered for the current and
voltage transformers, and the nominal device values.
2.
,1VSULPDU\
Ground fault values, primary.
The real portion, I
Nsw
, and reactive portion, I
Nsb
, of the (re-
sidual) ground connection current. The measured values
are converted from secondary to primary according to the
settings entered for the current and voltage transformers,
and the nominal device values.
3.
2SHUDWLRQVHF
Operating measured values, secondary.
The values of the measurement quantities that are present
directly at the terminals of the device are issued.
4.
,1VVHFRQGDU\
Ground fault measured values, secondary.
The real portion, I
Nsw
, and reactive portion, I
Nsb
, of the
ground connection current. The values of the measurement
quantities present directly at the device terminals are given.
5.
3HUFHQW
Operating measured values, in percent of nominal quanti-
ties.
The nominal quantities are determined by the version of the
MENU
Etc.
