Examples of safety measures
Installation of temporary conductor covers
With temporary conductor covers installed, you can get as close as 1.2 m to a line. This temporary measure can only be taken for a maximum of seven days.
Moving medium-voltage lines
Hydro-Québec moves lines using temporary H-frames. There are visual markers that the lines are energized (live) to remind you to keep at least 3 m away.
De-energizing a line means cutting power to it, so you can approach it safely. There are visual markers that the line is de-energized (dead).
