Actually, I driven around a day or two later to see the transformers ~ the line slaps are meek little things compared to the transformers.
” ... the line slaps are meek little things compared to the transformers.”
You’re NOT getting it. It’s the large ARCS that result FROM the line slaps. The transformers are INHERENTLY limited as to how MUCH current flows through the secondary (WHERE do you think the fault MIGHT form if it INVOLVES the transformer?) AND the branch circuits to the transformers on the distribution spur circuits are FUSED!
