If a live circuit contacts a pole during installation, what type of voltage may be set up at the pole's base?

When a live circuit makes contact with a pole during installation, it can create a situation where voltage is present at the base of the pole due to the distribution of electrical energy in the surrounding area. This is known as gradient voltage.

Gradient voltage occurs because electric potential decreases as distance from the source of voltage increases. If a conductor is energized and comes into contact with the pole, it can create a voltage gradient in the ground or along the pole. This means that different points along the pole or at its base will have varying voltage levels, which can be dangerous. The further you move away from the point of contact, the lower the voltage will be until it reaches a neutral level.

Understanding gradient voltage is crucial for safety because it can lead to hazardous conditions for anyone working near the pole, as it increases the risk of electric shock. This concept is important for both installation practices and safety protocols in electrical work.
