Clearance means the minimum safe distance that must be kept between energized overhead conductors and the ground, equipment, or other objects. This safety buffer is set to prevent accidental contact or arcing and depends on factors like the voltage level, environmental conditions, and conductor sag. It’s about ensuring you have enough space to work safely, not about the maximum distance or about how long a span is or platform heights. The option describing the minimum safe distance between energized conductors and the ground, equipment, or objects matches this definition.
