Precise impedance modeling of power cables is essential to ensure the stable and efficient performance of inverter-cable-load configurations, particularly in high-frequency switching scenarios typical of modern power electronics. As the switching frequency rises, parasitic elements-resistance (R), inductance (L), capacitance (C), and conductance (G)-exert greater influence, potentially affecting signal fidelity, energy transfer, and overall system reliability. This study introduces a structured methodology for determining both the primary and secondary transmission line parameters of single-phase power cables by employing the short-open test method.
