The voltage drop level of a grid refers to the amount of voltage lost as electricity travels through the grid.
Voltage drop is typically kept below 3% in distribution systems to ensure efficient power delivery.
Factors affecting voltage drop include distance, wire size, and current flow.
Voltage drop can be calculated using Ohm's Law: V = I * R, where V is voltage drop, I is current, and R is resistance.
For example, a gri...
