You're assuming the dinosaur fence operates on the same principal as a regular livestock electric fence. I put it to you that the Dino enclosures use alternating positive and negative stringer wires, where touching one won't do anything, but touching two will make a short circuit.
That would make a lot of sense, but as we can see the stringers are connected together, meaning they'd just short out if they were alternate polarities. To me this indicates that it's like a standard livestock fence, with an electrode in the ground somewhere and the circuit completing through the animal.
However, considering my 16'x48' pig enclosure required a three-foot rod to be grounded, a system large enough for a sauropod would need a lot of grounding. Considering this, the fact that they used a circuit-through-animal design indicates it probably wasn't the best way to do it.
Spared no expense...
Maybe the stringer spacers are polymer though. Like those separation bars you see on residential power lines
Maybe they’re polymer but they look pretty metallic and there’s an awful lot of them. Plus if the stringers are under enough tension for a full grown man to climb them they wouldn’t need separators.
