. The powers are positive if the real power and reactive power flow
into the protected equipment, assuming that this direction is set as “forwards” (Ad-
dress 0201, see Section 6.1).
• cos ϕ: power factor. The sign matches that of the real power.
• f: frequency in Hz.
•Θ/Θ

: thermal value ratio, calculated temperature rise in % of the trip tempera-
ture rise or limit temperature rise.

From the
Device Front
With a device ready for operation, first press the key. The 0$,10(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-
20.
.
Figure 7-20 Selection of Measured Values in the HMI — Example
The measured values are divided into the following groups:
1. 2SHUDWLRQSUL 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. ,1VSULPDU\ 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. 2SHUDWLRQVHF Operating measured values, secondary.
The values of the measurement quantities that are present
directly at the terminals of the device are issued.
4. ,1VVHFRQGDU\ 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
