RUT,
The reason you wouldn't find the words are because they are Electric pieces of equipment to maintain relieable power service to customers. Without a good up close picture it is really hard to tell, could even be a small Capacitor Bank there on the pole.
Don't want to try to explain as might even have you more confused..LOL
Usually a Recloser will have an Electronic Controller below on the pole with settings that are determined by an Electric Engineer and uploaded to control. I have seen in NV where they have Reclosers out in the middle of no mans land without controls, never have understood what purpose they were used for there. More problems this way too.
Not all states are done the same, but next time your power goes out when you are in the middle of a game on TV or watching a porn flick, count to 5 seconds, if it was only a momentary thing, the power will be back on. Substation Regulators also come into picture. Might be they are set at 20 sec or even 60 sec.
Now are you confused......sorry.
