Notes
Scope of application: Correctly dimensioning current transformers
When choosing summing current transformers, it is essential to take the energy balance into account:
To do this, consider the power of the current transformers minus the load of the cables. The total power of the inputs minus the power loss of the summing current transformer is the maximum power at the output. The power at the output of the summing current transformer minus the load of the cable and the required power of the measuring device must ultimately be greater than 0 VA.

The calculation tool assists in the selection of current transformers, but does not replace technical expertise. KBR GmbH accepts no liability for incorrect design.
Procedure:
1) Select what you want to calculate: current transformer, cable conversion transformer, or conductor cross-section.
2) Add the devices in the appropriate number and type. Alternatively, you can also enter values independently in the drop-down menu by selecting “Manual free value entry.” The fields highlighted in gray are filled in automatically. White fields must be filled in manually.
3) Check the green results area to see whether the performance of your selected current transformers is sufficient.
