    30. Summary Properties of Y and Z Fault Analysis Equivalencing Worked with steady state phasor/impedance models but ideas carry through to other network analysis

    31. Component Models (Primitives) Lines Transformers Machinery The primitive relates terminal voltages to terminal currents - differential equations for transients/stability - phasor/impedance models for sinusoidal steady state - may be nonlinear Models go with analysis needs Model detail must be balanced against data(parameter) availability/accuracy Modern software databases allow for complete detail
