One way is to install a two to one winding ratio Boost transformer fed with 120 volts and then ground one end of the secondary. Never saw one and you would probably have to make it yourself.

I have a variable transformer at my shop. It has a dial on the top that lets you drop from 120v nicely all the way down to 1 volt by turning the dial . It's all open windings so we only keep it around for no reason at all............

Another way is to fly to England.

It is also called an open delta transformer. But this is only on 3 phase.
You do not state where you measured the voltage, or what electrical system you were working on.

Hope you had your PPE on.

Measure 120V to neutral twice and add them together,... 240V

 

[radio208]

Are you measuring voltage with a digital meter or wiggy? With a wiggy, you might be seeing 208 volts as in neutral to delta phase (high leg).

I use to work on a single phase center grounded 480v secondary that provided 240V to neutral. It was a very old street lighting system and the center tapped 480V was provided by the utility. There were no line to line loads.

Just about anything that will run on 240v to N will run on single phase 240.

Three phase delta has one leg that is 200 and something volts.

Europe’s power is 240 volt to neutral. Remember neutral and ground are not the same thing.

You mean those electrons won't get lost without a white wire?

and 50Hz

Hello guy, new here and new to the workforce. Silly question, are you able to get 240V from Line to Neutral. If so how? I have heard of 240V L TO N but I dont understand how that is possible

Isn't there a weird system it's either grounded b phase or high leg or something where you get 240 I can't remember off top of my head

 

[gpop]

If you really need 240v to N then use can use a 240 to 240 transformer. Most of the time we will use it to convert 240 single phase to 120/240 but will a little rewiring you make it 240V to N

High leg delta you get 208V line to ground / neutral on the high leg, 120V line to ground / neutral on the other two legs.

Corner grounded 240V delta you get 240V line to ground on the two ungrounded phases, but there is no neutral.

To get 240V to neutral, you'd have to have either a 415V wye like @oldsparky52 posted, or I suppose if you had a center tap on a 480V winding, that would be 240V phase to neutral. You could see this at the transformer terminals, but I don't think you'd see it past there - not that I know of. If I did see it and verified the meter's not messing with me, I guess I'd wonder if there's a miswire in a transformer.

That's right don't see it much. Thanks

It's al over the place in the older areas of Phoenix. Even in some older residential neighborhoods.
Apparently they installed it for the new fangled air conditioning systems that were all the rage in the 60s
