3-Ф Delta Balanced
Example: For symmetrical loads like motors, the connection is
simplified with only one phase measurement and assuming the same
voltages/currents on the other phases.
Energy Study
Load Study (no voltage measurement)
Nominal Voltage
In load studies only, select a nominal voltage from the list. If a voltage
is not shown in the list, enter a custom voltage.
The nominal voltage on load studies is used to calculate the pseudo
apparent power:
nominal voltage x measured current
Set the nominal voltage to off if the apparent power readings are not
required.
Voltage Ratio (only in energy studies)
Configure a ratio factor for the voltage inputs when a potential
transformer (PT) is in series with the voltage connections such as
when you want to monitor a medium-voltage network. The default
value is 1:1.
Nominal Frequency
Set the nominal frequency to be the same as the power line
frequency, 50 Hz or 60 Hz.
Current Range
Configure the current range of the attached sensor. Three ranges are
available:
• Auto
• Low Range
• High Range
When set to Auto, the current range is set automatically and depends
on the measured current. Low Range is 1/10 of the nominal range of
the attached current sensor. For example, the low range of an
iFlex1500-12 is 150 A. High Range is the nominal range of the
attached current sensor. For example, 1500 A is the nominal range on
an iFlex1500-12.
