  <power_bus> a seas:ElectricalConnection ;
    seas:connectsSystem <power_line_1> , <transformer> , <power_line_2> .

Only electric power systems and electrical connection points are connected through an electrical connection. A connection between electric power systems is not necessarily an electrical connection.

Any electric power system that exchanges electricity through an electrical connection is connected at least through one of its power connection points to the electrical connection: if:

  <power_system> a seas:ElectricPowerSystem .
  <power_connection> a seas:ElectricalConnection .
  <power_system> seas:connectedThrough <power_connection> .

  <electric_vehicle> a seas:ElectricPowerSystem ;
    seas:connectsAt <plug_high_voltage> , <normal_plug> , <three_phase_connection_point> .
  <plug_high_voltage> a seas:ElectricalConnectionPoint .
  <normal_plug> a seas:ElectricalConnectionPoint .
  <three_phase_connection_point> a seas:ElectricalConnectionPoint .

Any system connected through an electrical connection is connected at one of its electrical connection points to the electrical connection: if:

  <system> a seas:System .
  <system> seas:connectedThrough <connection> .
  <connection> a seas:ElectricalConnection .

then there exists _:connectionPoint such that:

  _:connectionPoint a seas:ElectricalConnection Point ;
    seas:connectionPointOf <system> ;
    seas:connectsSystemAt <connection> .

An electrical connection point describes an electric signal, and the electricity that enters/leaves the electric power system. An electrical connection point only belongs to an electric power system, and connects it through electrical connections. A connection point of an electric power system is not necessarily an electrical connection.
