← ScienceWhich outcome reduces arcing across separate, inductive motor windings?
A)Inserting coil end-turn phase insulation✓
B)Using lower resistance winding material
C)Increasing lamination air gap distance
D)Overlapping the slot liners completely
💡 Explanation
Inserting optimal insulation boosts the dielectric withstanding using the capacitance discharge mechanism, because voltage stress decreases across windings; therefore reduced likelihood of arcing, rather than lower conductor resistance or gap distance altering fields.
