The concept of three phase alternating electricity refers to the relational phase differential of three alternating current single phase sine waves, each displaced 120 degrees of phase angle from the other.

still the is a three wire DC transmission system.
usually DC transmission used for several resone but the most know one is when the transmission line is longer than 600 km
What else can I help you with?
In a 3 phase 480 panel what voltage should you get phase to phase?
The voltage you are referring to is a 'line-to-line' voltage ('line voltage'), as there is no such thing as a 'phase-to-phase' voltage.480 volts. In real life, the voltage will vary slightly by up to 3% (14 V) on a properly sized circuit. Line to neutral will measure 277 volts, plus or minus 3%.
What is called an effective voltage in Alternating current and if you mention 115 V ac 3 phase means peak voltage is 115 or it is an effective voltage?
115 is the RMS voltage. The actual voltage is a sine wave from -167 to +167 relative to ground. RMS stands for root-mean-square, and it a way of saying that 155 Volts of DC would do the same work on the same sized load. There can be up to 3 phases, and they are the sine wave, shifted by a part of the curve. In most houses, there are 2 phases, and the voltage to ground for each is 110 to 120 V RMS. The voltage between the 2 is 230-240VRMS. 3 phase gets very complex. Each phase is 115 to ground or neutral. 3 PHASE 115V AC EACH PHASE IS 120 DEGRES PHASE SHIFTED THE EFFECTIVE VALUE IS .639 X 115 THE PEAK VALUE OF PHASE IS 1.41X RMS VALUE.
Why floating neutral in a three phase supply is undesirable?
Floating neutral in 3 phase supply is undesirable as if the same thing occurs then there will be bad effect for all single phase equipment which we are using as phase to neutral voltage will exceed from its normal value and it will harm the equipments.
If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage.CommentThere is no such thing as a 'phase to phase', or 'phase to neutral' voltage. The correct terms are 'line to line' and 'line to neutral'. So the above answer should read: line voltage/1.73= line to neutral voltage = phase voltage.
How do you derive three phase single way?
3 phase /sqrt(3) * 30 degree phase shift = single phase.
In a 3-phase high voltage star-star connection 140KVA transformer and load phase voltage is 115v and frequency is 400hz what is the total load current?
Maximum load current on a 140KVA, three phase transformer when the output voltage is 115 v phase to phase is: 140kva / sqrt (3) / 115 = 703 Amps. frequency does not matter here.
Can you run 575v with household power?
Yes, but you would not want to. 575V is simply 115V run through a 1:5 transformer. (5x 115) 115V @ 20A AC = 575V @ 4A AC Usually the devices (welders) on the 575V side are running 10 or 15A, so: 575A @ 15A AC = 120V @ 75A (A 75A breaker for home use isn't common) 575 volts is a 3 phase voltage. The actual 3 phase voltage is 600/347 to ground. If you have a device that requires 600 volts check to see if it is single phase or three phase. For 3 phase 600/347 you will need a separate service.
Want to use 3 phase at home?
I think you will find (in the US at least), that almost all utilities will refuse to provide 3-phase power to a residence. If you have just one thing such as a motor that you need three-phase to run, you can purchase a phase convertor to convert your single-phase to 3.
What part makes torque in a 3-phase motor?
The whole thing once you apply electricity.

Why is there 115v on neutral wire in receptacle when 208v circuit is on?
The presence of 115V on the neutral wire in a 208V circuit could indicate that there's a voltage imbalance or a faulty connection in the wiring. In a three-phase system, if one phase is not properly balanced or there is a poor connection, it can cause a voltage reading on the neutral. Additionally, if there is an unintended return path or a ground fault, it may also lead to a voltage reading on the neutral. It's important to investigate this issue as it may pose safety risks or indicate underlying electrical problems.
230V line to line a single phase?
Yes. 230V line to line is considered single phase power. The 115v half part of that is called split phase. It should not be called two phase, as it is one phase that has been center tapped and grounded at the neutral point - it is still one phase power.Answer230 V is the standard nominal voltage for residences in Europe. 230 V is the line-to-neutral voltage (phase voltage). Low-voltage distribution is by three-phase, four-wire, system with a nominal line voltage of 400 V and a nominal phase voltage of 230 V.
