Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
PhaseSequenceMeasurementFunction ⊑ DesignedFunction
Realized in
PhaseSequenceMeasurementProcess ⊑ MeasurementProcess
The identity-giving function is to measure and indicate the phase sequence in polyphase electrical systems - specifically determining the order in which phase conductors reach their maximum instantaneous voltage. This is a specialized electrical measurement function distinct from general voltage or current measurement.
2 Genus DeterminationDeterminação do Gênero
Instrumentbfo:Object (BFO_0000030)
Following the ISO 15926 hierarchy, the direct parent is 'ELECTRIC VARIABLE MEASURING INSTRUMENT'. This maps to ElectricMeasuringInstrument as the most specific appropriate superclass. While no instrument classes are yet enriched in our ontology, this is more specific than jumping directly to MaterialArtifact. An electric measuring instrument is a single causally unified artifact designed for electrical measurements.
3 Differentia SpecificaDiferença Específica
∃bearerOf.PhaseSequenceMeasurementFunction ⊓ ∃hasInput.InformationContentEntity

Specifically measures the sequence order of phase voltage maxima in polyphase electrical systems, distinguishing it from other electrical measuring instruments that measure voltage magnitude, current, power, or other electrical parameters.

The key differentia is the specific PhaseSequenceMeasurementFunction and the requirement for polyphase input. This distinguishes it from all other electrical measuring instruments which focus on different electrical parameters or work with single-phase systems.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts are fundamental to any phase sequence meter: phase detection circuitry to analyze timing relationships, electrical connections to access the system, and indication means to communicate results.
