Note the photocontrol in front of the regulator and the smaller can which is the oil switch behind the regulator. Juice comes out of the regulator and ends at the oil switch which opens or closes the circuit. Its named so because the contacts are dipped in oil, probably to prevent arcing as it opens or closes.

is the Switch powered by some sort of electromagnet?...like a Giant Relay/Contactor?

I am not 100% sure how it works inside, but on series systems the lamps are turned on by either a single photocontrol or a timer.

The switch is a basic contactor, with the oil serving as a coolant and an arc quench agent, reducing the wear on the switch faces, but without the cost of having a pressurised switch which uses SF6 as the quench agent. They normally will rust to pieces before they wear out mechanically or electrically.

I found this reg too by follwwing the series wire.

What happens if one of these regulators dies? Do they even still make these things?
streetlight98   [Oct 20, 2011 at 11:37 PM]
well i guess it's time to switch to 21st century multiple wiring then.......

They still make series regulators for runway lighting but I'm not sure if the pole mounted streetlighting regulators are still made.
Silverliner14B   [Oct 21, 2011 at 06:28 AM]
Yes I believe series regulators for street lighting systems are still made.
gailgrove   [Oct 21, 2011 at 07:22 PM]
What companies make them?
streetlight98   [Oct 21, 2011 at 08:59 PM]
Probably Advance, but I don't know.

I know of "Specialty Transformer" makes pole regs like this, as well as airport regs that have a brightness control. LED airport markers are now made to operate on 6.6A, so I bet LED streetlights could be made for series too.

That would be an odd sight. Shocked

I know one street in Los Angeles that has a mix of series incandescents and MVs, AND multiple 120v LEDs on the same row of freestanding wooden poles! The top of all the poles have a single wire for all the series lights, and the DWP installed a second 120V line just below the series line on several of the poles that got LED replacements. Odd!
