What is the minimum safe distance to construct a building near HT lines?

The minimum safe distance for constructing a building near high-tension (HT) power lines varies by country and local regulations, but a common guideline is to maintain a distance of at least 15 to 30 meters (50 to 100 feet) from the edge of the right-of-way of the lines. This distance helps ensure safety from electrical hazards, as well as issues related to electromagnetic fields. It is essential to consult local building codes and utility regulations for specific requirements in your area.
