Which risk increases when a single-phase load is unintentionally connected between two phases of delta-configured three-phase power?

💡 Explanation

When a single-phase load connects line-to-line in a delta system, unbalanced currents flow because the load draws current from those two phases, overloading the transformer windings and causing uneven heating. Therefore overheating results, rather than resonance, distortion or sags, given direct connection between phase lines.
