Thanks. Seems like some (relatively cheap) temp sensor and feedback systems need to be installed? Surprised capital equip this expensive doesn’t already have. Low cost insurance.
Yes. That would stop damage from an attack on the vulnerable radiators, piping and pumps.
A shot into the transformer itself would short out the windings and provoke a catastrophic arc, welding windings together and possibly starting a fire, if not an explosion.
The transformer is much more robust that the radiator, though.
My solution?
Plant trees around the substations. They prevent clear sighting of a rifle, and branches would cause random deflections of any shots fired.
Perhaps not as elegant as a technological solution, nor a permanent a solution as eliminating every terrorist, but something cheap, easy and esthetically pleasing to the global warming crowd...
As we used to say back in the TV repair biz: “A $200 picture tube will blow to protect a 15¢ fuse.”
