Configure the object properties of the block (e.g. LOWER_SETPOINT). For this pur-
pose, right-click the Limit input of the block and select Object properties from the
context menu.
Observe the working range of -180
°
to +180
°;
the value 100 (%) corresponds to
360
°
.

The set value 12.5 corresponds to an angle of 45
°
.
2.4.4 Measurement U 1.packet
This packet serves to measure an individual voltage. The function provides the r.m.s.
value of the fundamental component.
2.4.4.1 Description
The frequency of the voltage is determined from the input signal. If the secondary input
voltage on the device falls below 10 V
eff
, the frequency is marked as invalid. The over-
flow occurs when the secondary input voltage on the device exceeds 120 V
eff
. The
rated value of the frequency is taken from
36\VWHP'DWD
.
Routing of the measurement input to the respective measured value channel Voltage
and the routing of the measuring results is performed with DIGSI
®
.
Specifications for secondary transformer voltage are made in the properties dialog box
of
088B
.
Information on allocation can be obtained from the SIPROTEC
®
system description/1/.
