Technically, the intensity of the electromagnetic fields radiated from electrical transmission lines becomes smaller as the distance from the cable increases, but it never reaches zero. Despite many studies made on the effects of magnetic fields, there is no definitive guide as to what harmful effects high voltage fields have on humans or other living things. The level of risk in being exposed to these fields cannot be categorically stated.

See Related Link below for a cool video of a lineman working on an energized line.

How do you test the 11KV HT cables?
The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.
What are the names for high voltage power cables?
Electrical conductors
What is expected life span of high voltage underground cables?
10yrs
Why High voltage test for cables?
High voltage testing is performed to confirm the integrity of a cable's insulation. It is always carried out after a new cable has been installed and terminated, or whenever a new joint is installed.
Why high tension cables conductor are circular?
High-voltage conductors are circular to evenly-distribute the electric field that surrounds them in order to prevent breakdown.
When splicing high voltage cables what is the minimum distance between splices?
30 cm
What do you use to mark the high voltage cable?
Why is use the triangle system in high voltage cables
What is the minimum distance allowed between two joints in a high voltage cable of 66 KV?
the minimum distance between two cable joint 2 meter (refer IEC 60052-4)

The high-voltage section of a unit substation contains devices called to which the incoming high-voltage cables are terminated?
potheads
What color of cables represents high voltage in hybrid vehicles?
Black.
What is expected life span of high voltage underground cables?
10yrs
Define methods of stress control in high voltage cables?
A method of stress control is controlling the distribution of dielectric stress. Uniform distribution of dielectric stress may be achieved in high voltage cables by surrounding the high stress areas of the high voltage cable with a tube of high permittivity material that makes contact at one end with a ground electrode contacting the shield of the high voltage cable.
How can you identify the high-voltage system in most hybrid vehicles?
The cables and connections are bright orange.
Distance between ehv lines?
The distance between high voltage lines is governed by either a switching impulse voltage or lightning impulse voltage. The distance between lines, or lines and tower must have a high enough dielectric strength to avoid flashover at these voltage. Air can withstand a voltage of 3kv/mm.
