Deep End Era. Engineering with Sankalp · Oct 29, 2026 · 1h 8m

On the hottest week of the year, the oil sample from the main step-down transformer at the Al Sahil Gas Complex comes back with acetylene in it.

Along the way we learn how high-voltage breakers kill an arc in milliseconds, why SF6 is both miraculous and a problem, and how a transformer ages.
