The First Safe Look: Is That Downed Line Live?

<p></p><p>When a storm passes, the deadliest moment isn&#39;t the wind — it&#39;s the window right after, when damage is everywhere and nobody yet knows which downed spans are still carrying lethal voltage. This deep dive walks through &quot;The First Safe Look,&quot; a white paper on flying solar-blind ultraviolet cameras on drones to spot arcing, surface tracking, and corona on storm-damaged transmission and distribution assets — in full daylight, from a safe standoff, before a single crew member approaches.</p><p>We get into what daytime UV genuinely sees (the energized downed primary arcing in a yard that never drew enough current to trip a relay — a textbook cause of public electrocution), and what it can&#39;t (the quiet service drop backfed from a rooftop solar array, sitting live and silent at 240 volts). The honest version: UV finds the arc, not the voltage. That&#39;s exactly why it works as the first, fast layer of a storm-response safety protocol — not a replacement for test-before-touch.</p><p></p>
