    In power systems, cable arrangements strongly influence electrical, thermal, and spatial performance. Underground cables are typically installed in trefoil or flat configurations, with cleats placed at intervals to ensure stability under fault-induced electromagnetic forces. However, these arrangements may produce induced voltages and induced currents in the sheath, reducing reliability. Floating conductors, such as ungrounded cleats, can further enhance electromagnetic coupling and generate additional induced voltages. This study uses Finite Element Method (FEM) simulations on a cross-bonded trefoil cable model to analyze these effects. Results show that induced voltages arise from the combined action of electric and magnetic fields and are strongly affected by cleat conductivity. The findings indicate that induced voltages on floating conductors may accelerate insulation degradation and increase safety hazards, highlighting the need for proper cleat design and bonding practices.
