As a power distribution system for remote supply at the field level the power bus provides large savings potentials regarding layout costs, assembly and start-up. Instead of the point-to-point distribution from the control cabinet to the individual load carrying device, the power bus supplies not only power, but also distributes control voltages or data to each device.

For an efficient design of the system and in order to assess the necessary circuit protection measures, the results of electrotechnical calculations for load, voltage drop and short circuit are performed.

The podis® PLAN planning tool supports you in configuring the power requirements for your specific power bus system.

The graphical presentation helps you determine the optimal design for your power bus, including the ideal feed-in point. System failures caused by incorrectly specified protection devices are also prevented. You avoid the common errors of “over-specification” of the cables due to "safe designs" based on experience. Inconsistencies or inferior configurations are recognized immediately during design phase. Thus you avoid cost-intensive errors beginning in the preliminary planning stage.

Project management

The project explorer helps you to clearly organize your system documentation. podis® PLAN is an effective management tool for projects and sub- projects.


Entering network and infeed parameters

The user first enters the network or feed-in parameters required for supply of main and auxiliary power to the power bus:

  • Rated mains voltage AC/DC
  • Permissible voltage drop
  • Ambient temperature
  • Conductor loads


Input of group protection, cable and load parameters

You can graphically configure your systems including the assignment of the components. Protective devices, cable and load parameters can be selected and entered conveniently in the input templates.


Infeed parameters:

  • Feed-in position on the power bus
  • Selection and setting of the protective devices
  • Feed-in short-circuit current IK


Load parameters:

  • Connection position on the power bus
  • Power consumption and load current
  • cos phi
  • Permissible voltage drops
  • Simultaneity factor
  • Load determination


Installation parameters:

  • Layout type
  • Cable cross section and number of loaded cables
  • Ambient temperature
  • Length and cross sections of the supply cables and the power bus


podis® PLAN calculates the permissible static load for the system configuration and outputs the following measurements based on the parameter inputs:

  • Total power and total current (AC and DC)
  • Short-circuit current (AC and DC)
  • Voltage drop
  • Current carrying capability
  • Total length and segment lengths
  • Metered lengths



The results are output graphically or in tables. The values are calculated in the background during input; overload and errors are highlighted in color in the diagram. For documentation purposes, the results can be saved or printed using the project explorer.
