What determines the minimum distance that any part plant and machinery has to be kept from overhead electricity lines and explain why a distance should be kept?

The minimum distance that plant and machinery must be kept from overhead electricity lines is determined by safety regulations, which typically take into account the voltage of the lines and the type of equipment being used. This distance is crucial to prevent accidental contact that could lead to electrical shock, electrocution, or equipment damage. Maintaining a safe distance also helps to minimize the risk of arcing, which can occur when machinery gets too close to high-voltage lines, thus ensuring both worker safety and operational integrity.
