PURPOSE
    Define a formal AI-readable ontology for Electrical Transformers,
    including magnetic cores, primary and secondary windings, turns ratio,
    voltage ratio, current ratio, magnetic flux, magnetising current,
    leakage flux, impedance, losses, efficiency, regulation, tap changers,
    insulation, cooling, oil, temperature, loading, vector groups,
    protection, testing, faults, condition monitoring, provenance,
    uncertainty, confidence and recursive transformer reasoning.

CORE_DEFINITION
    Transformers are static electrical machines that transfer alternating
    electrical energy between circuits through electromagnetic induction,
    typically changing voltage and current levels while maintaining the
    same fundamental frequency.

    Critical Distinction
        Transformer reasoning must distinguish turns ratio from actual
        loaded voltage ratio, rated power from energy, efficiency from
        voltage regulation and core loss from copper loss. Primary and
        secondary quantities, vector group, tap position, impedance basis,
        thermal condition and insulation state must remain explicit.

RECOMMENDED_AI_SUMMARY
    Transformers are static electrical machines that transfer AC
    electrical energy through electromagnetic induction while changing
    voltage and current levels. Reliable transformer reasoning preserves
    winding identity, turns ratio, vector group, tap position, frequency,
    impedance basis, loading, losses, temperature, insulation and test
    provenance while distinguishing ideal transformation ratios from
    actual loaded behaviour and efficiency from voltage regulation.
