6.3 Parameterizing the device
58 Equipment Manual, 09/2022, L1V30415168B-03
"Voltage Input" parameter
The "voltage input" parameter specifies the values for the voltage input. Which values have to
be set depends on the type of measurement.
Selection Range Factory
Is voltage measurement performed via the voltage
transformer?
• Yes:
If measurement is performed via the voltage
transformer, the device must know the voltage
transformation ratio. For this purpose, the primary and
secondary voltage must be entered in the fields
"PRIMARY VOLTAGE" and "SECONDARY VOLTAGE".
On switchover from direct measurement to
measurement using the voltage transformer, the
device accepts the last set reference measuring voltage
as the secondary voltage and as the primary voltage.
• No:
If measurement is performed directly on the low-
voltage system, the following must be considered:
When changing from measurement using the voltage
transformer to direct measurement, the device accepts
the last set secondary voltage as the reference
measuring voltage.
"Current Input" parameter
The "Current input" parameter specifies the values for the current input.
Current measurement is performed via the current transformer only. The transformation ratio
of the current transformer must be specified.
For this purpose, the primary and secondary current must be entered in the fields "PRIMARY
CURRENT" and "SECONDARY CURRENT".
Freely adjustable in the range: 1 A to 99999 A
