v1.0 2017-08-24 The SEAS Electric Power System ontology The SEAS Electric Power System Vocabulary defines: 1. Electric power systems that consume, produce, or store electricity, 2. electrical connections between electric power systems, where electricity is exchanged, and 3. electrical connection Points of electric power systems, through which electricity flows in/out the power systems. Gabriel Santos Lynda TEMAL 2016-06-06 seas testing An electrical ballast is a device placed in line with the load to limit the amount of current in an electrical circuit. It may be a fixed or variable resistor. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube, which would otherwise rise to a destructive level due to the negative differential resistance artifact in the tube's voltage-current characteristic. Ballasts vary greatly in complexity. They may be as simple as a resistor, inductor or capacitor (or a combination of these) wired in series with the lamp; or as complex as the electronic ballasts used in compact fluorescent lamps and high-intensity discharge lamps. (source:wikipedia) Electrical Ballast testing An electric power transmission system is an electric power system that is capable of transmitting electricity. Usually to transmit electricity on a certain distance within an electric power network, or to transform it. Sistema de Transmissão Electric Power Transmission System testing The class of properties that are quantifiable and have a quantity kind of electric conductance. Electric Conductance Property Electric Power Line testing An electric power line is an electric transmission system that is capable of transmitting electricity on a certain distance within an electric power network. An electric power line must be connected to two power connections, although this requirement cannot be modeled using OWL axioms if we want to remain in a decidable fragment. testing The class of electric power systems, i.e., systems that exchange electricity (i.e., electric power) with other systems. Electric power systems may consume, produce, or store electricity. Such systems are defined by subclasses of electric power system. Electric power systems that dissipate energy are thermodynamic systems (i.e., they can then dissipate heat). Electric power systems can exchange electricity with other electric power systems. These exchange are only possible through electrical connections between electric power systems. Electric power systems can have sub power systems: - The consumed or produced electricity of subsystems contribute to the consumed or produced electricity of the supersystem; - the stored electricity of subsystems contribute to the stored electricity of super systems.

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> . ``` then there exists `_:powerConnectionPoint` such that: ``` _:powerConnectionPoint a seas:ElectricalConnectionPoint ; seas:connectionPointOf <power-system> ; seas:connectsSystemThrough <power_connection> . ``` testing A split-phase power bus is a connection composed of three wires (plus the protective earth): - wire for the hot 1 phase; - wire for the neutral; - wire for the hot 2 phase.

An electrical connection point only belongs to an electric power system, and connects it through electrical connections.
