Two positions are provided for entering the nominal voltage and thus also the input range. The first,
Primary value
,
represents the actual voltage at the measurement location. The second,
Secondary value
, indicates the voltage at
the inputs of
SICAM Q80 7KG8080
. If the measurement is performed without a converter (no check in the box
Converter
), then the primary side presents a list of possible nominal voltages which can be connected directly.
Voltage values
Nominal voltage:
Nominal line voltage
Serves as indicator variable and not used for calculations
Operating voltage:
Expected or declared line voltage
Normally equal to the nominal voltage, especially at low voltage
The operating voltage is used for all subsequent calculations and value
limits.
If the measurement is carried out with a converter, the list shows a selection
of primary voltages, which you can define yourself under
. In parallel to this, the corresponding secondary voltage at the
device inputs is indicated.
Converter data base
Depending on the input configuration, the nominal voltage is interpreted either as the conductor voltage or as the
voltage to the neutral point. This saves the trouble of value conversion. When you switch between different input
configurations, the values are adapted automatically.
