Voltage affects which of the following in power system design?

Voltage sets the electrical stress that components must withstand, so insulation is chosen to handle that stress. Higher voltage means insulation must be thicker or made of higher‑quality material to prevent leakage, breakdown, or overheating. It also increases the risk of arcing between conductors, so the physical separation in air and along surfaces (clearance and creepage distances) must be increased to keep the electric field from reaching breakdown levels. For people, voltage dictates the required safety measures: minimum approach distances, appropriate PPE, insulated tools, barriers, and lockout/tagout procedures all scale with voltage to protect against shocks and arc flash. Because voltage influences insulation requirements, conductor separation, and safe working practices, it affects all of these areas.
