Node Names for Measuring LocationsATPDesigner uses node names
and TACS variables to identify currents and voltagesmeasured in the
power network. In addition currents and voltages will be
calculatedbased on measured signals. The number of available nodes
depends on the selected
Output Signals and on the Measuring Locations used as part of
the power network.ATPDesigner supports up to 5 pre-defined
Measuring Locations assigned to theCircuit Breakers Cb1..5. The
Measuring Locations can be assigned to the circuitbreakers Cb1..5
using by the user:
Open the dialog Network Configuration via
y the Right Mouse Button Menu,y the toolbar button ory the main
menu Power Network, menu item Network Configuration.
Please select one of the entries in the combobox Measuring
Location.
In the example shown above Measuring Location M1 has been
assigned to the circuitbreaker Cb1, Measuring Location M2 is
assigned to circuit breaker Cb2. Please note,
that e.g. Measuring Location M1 can be assigned to different
circuit breakers e.g.Cb1 or Cb2.
Note:
The Ground Compensation Factor kG is used below to calculate the
phase -to-groundfault impedances. This factor must be set in the
dialog Signal Analysis Settings and is

independent of the ground compensation factors used for the
Single-Circuit Lines.Please note, that Probes can be also used to
measure voltages and currents. Pleaseread the corresponding chapter
for more information about the Node Names ofProbes.
