In a 3 Phase service I have seen 240v between phases and a 208 to ground wild leg, What are some other combinations and where do they use the wild leg?

Search for high leg (27 hits) or 4-wire delta (4 hits) at this site.

Note that “Bø” {or sometimes Cø} can also be called Stinger / Red / Orange / Purple / Power / Wild / Bastard / High Leg

Read through Scott35’s 3 Phase Delta Transformer Schematics in Technical Reference Area of this board.

Also see: home.att.net/~benmiller/elecsys.htm

Utility availability of this service type is usually limited to small, remote overhead systems.

Other non-symmetrical 3ø configurations are the corner-grounded variety.

I was unable to find any data in the technical Reference area.

Al,

Did you set the selection to see all topics?
We are working on a way to have them continuously visible regardless of date, but this works for now. Look at the thread in that area for Instructions if you're not sure what I mean.

Alda,
The wild leg is ONLY useful in configurations that do not require a neutral, such as 3 phase equipment, or 240 volt loads with no neutral, otherwise you burn it up.

You ONLY have a high leg in Delta systems (open or closed) because you tap mid phase of one coil (between A and C)

That's why the Wye is the popular form today, it creates no high leg and all 3 phases are useful with the neutral.

You often see 199 volt high legs, this is from 230 volt systems. Phase to ground voltage of A or C phase X 1.732 = phase to B voltage.

Al,

Take a look to see if this is what you are looking for.

Thanks for the answers, Bill great transformer drawings, but still not sure where they are used. On a 3ph system 240v between phases and measuring "120v to grd, 120v to gnd, and 208 to gnd", where would the 208v to gnd be used?

Aldav53,

The high leg (208 to ground) exists as a result of the center tap, but is not used to supply loads.
