Dear Forum Members:
I'm a college engineering student looking for some information on line voltages for street lights and other outdoor lighting systems such as parking lot lighting, walkway lighting, etc.
We're doing a project where we successfully developed a prototype that operates on a 110V system. Now we need to cover the other voltages to prove our theory.
According to a Planner at our local electric utility (Florida Power & Light) the following voltages are the services they provide:
120/240V 1P,3P
120/208V 1P,3P
240/480V 1P
277/480V 3P
It looks like we need to develop at least two more, maybe three, prototypes at considerable effort and expense. We just want to make sure we are not wasting time and money here.
Our questions are:
Of the above voltages, are they all used for street lighting?
Do we really need to accomodate 208, 240 and 277?
We know we need a 110V system and a 480V system because that's what we find around town. How about those in the middle?
A Switch Mode Power Supply (SMPS) is not feasible because it adds cost, space, heat, power consumption, etc. to the device. Requirements on the project include the ability to adapt to all existing AC systems without being cost-prohibitive.
Thanks in advance. This looks like a great venue.
