240 3 Phase

In both the power delivered is calculated by multiplying pressure (force) times flow (speed). Three Phase has three separate circuits with phases 1Degrees apart. You need three separate transformers, one for each phase.

Depending on whether the circuit is Wye or Delta, . Which might explain why you see 240V between the neutral and phases.

Please recheck voltage again to make sure that this is the case.

In other case you should have either 277V line voltage or 415V phase .

So if A-B, B-C and C-A are all 2volts, then A-N and C-N will both be 1volts, but B-N will be 2volts. Other types of three - phase supplies are wye connections, ungrounded delta connections, ghost leg configuration delta connections . It is also used to power large motors and other heavy loads. This configuration is older and is being.

W) will operate on this voltage configuration. Single Phase Three Wire Electrical Service. Also known as an Edison system, split- phase or center-tapped neutral. This is the most common residential service in North America. If it becomes necessary to change to another configuration, refer to the appropriate diagram and information on the following pages: Page 42: (OPTION A) 208- 2VAC, - phase , 4-wire.

Three - phase power is supplied by four wires. Three hot wires carrying 1volts of electricity and one neutral. It is the AC equivalent of the original Edison three -wire direct- current system.

In North America, individual residences and small commercial buildings with services up to about 1kVA (4amperes at 2volts) will usually have three- wire single-phase distribution, especially in rural areas where motor loads are small and uncommon. In rural areas where no three - phase supply is available, farmers . All the 120V loads load up the A-C phase. I also know that between any two phases you get 240.

The 2volts is the measurement from line to line and the 1volts is measured from either line to the neutral or grounded conductor. That is one phase (live) and neutral (return). The third prong is earth ( ground).

If something requires 415v to operate it will be connected between two phases (live).
