The tape or wire would have to be pretty low, assuming nothing would dig under, with strands pretty close together, going high enough to prevent jumping.
They are common place rurally; they can be a fence all by themselves for horses, cows, sheep, etc., or they can protect a fence from cows, or they can bolster a weak fence; it's costly to fence in large areas.
My electric fence is rarely on; just the site of the string keeps the horses from leaning on or kicking the fence.
If you are in a more populated area where electric fence isn't common, be careful about using it on a perimeter fence. In the 90s, I was living in the Mojave Desert with zero neighbors. A family built a house across from my place and down the road. Since my dogs regularly dug under our fence, we put an electric wire on the inside, about 6" off the ground, to keep them from digging out since there were actual neighbors to harass. The new neighbors didn't restrain their dog, though; it dug under the fence and got stuck one day. The wife reached inside the fence to pull him back, touched the hot wire, and sued us. It took 3 years before the court system finally threw her suit out. Electric fence was uncommon in that area, and nobody seemed to know how to deal with it in court.
No harm came to the wife or the dog; my boys used to touch it on purpose.
Anyway, you could try using some plastic "step in" posts; I can get them locally, and they are also available here:
