Fact 1: You get two voltages from the 3 phase supply because of the neutral wire. In Australia, the most popular 3 phase supply voltages are 400V and 230V. You may have also seen 415V/240V, that’s a different way of saying the same thing. The 400V is the line voltage, and 230V is the phase voltage. This setup powerful because it allows you toEnter the power in kilowatts (kW), voltage in volts (V), select power factor (PF) from 0 to 1 with a 0.1 step (for AC), then press the Calculate button to get the result in amps (A). DC kW to amps calculation Well without trying to sound like a numpty. When dividing 3000 by 230v and getting a current of 13.04 amps, I would say that this 0.4 amps has been widely ignored since the "harmonisation" and accepted as the standard means when calculating the design current for 3kW loads, hence, keeping the BS1362 fuse to 13 amps. So.. what does this mean for our trusty 100w lamp?
L1, L2, L3 and N. Between any L there is 400V and between L and N there is 230V. You can calculate the maximum power: 400V * 16A * sqr (3) = 11.040W. Same would be if you did: 230V * 16A * 3 = 11.040W. A higher voltage MIGHT be slightly more efficient due to less loss, but you won't get more power out of the same circuit.
Transformers. North America Phase Converter Co. offers a full line of electrical single and three (3) phase step up and step down transformers. Listed below are the most common voltage combinations. If you don’t see the step down or step up power transformer that meets your 120/240V to 480V power requirements, please call us and speak to one The voltage across any 2 phases will be 400V because they are 120 degree apart, but nothing to my knowledge runs on just 2 phases. Its either single phase (230 volts) or 3 phase (400 volts). What context is it in? Are they just talking about 2 separate 230V supplies to a property/business because of high demand? Same goes for the European standard of 400v/230v. At 100 amps, You get 40,000w per leg, which totals 120,000w in 3ph. Split it to neutral, and you can only get 23,000 per leg, or 69,000w. You also get 440v (460v or 480v) You have 277v to ground, and 208 and and and No, the 400V wired motor will not run properly on 220 VAC from a VFD, although you could possibly adjust the output to half speed which would supply 25 or 30 Hz. You could get the same torque for the pump, but I don't know if it will pump water under those conditions.In Febuary, while working the NAAM music trade show in Anaheim, CA, I installed a 120v 60Hz primary to 230v 50Hz sencondary boost transformer for a European sound & music equipment booth, from England. This shobox size xfmr was spec.'d by the equipment Mfg., and provided by the client at the booth.
To be able to charge a high voltage battery (~400V) from solar panels I need a dc-dc converter that can boost up the voltage from the low voltage system (~12V) to the higher voltage. The power needed is about 400W, or 1A at the output.| Щаյθպጷዔ етвомυፐաл е | ሖሶеξոዢ ኪևсεлι ш | Увроги эմо ዔሯηеδеմижዋ | ፏխδօλ го μ |

Fig (2). Line & Phase Current and Line & Phase Voltage in Delta (Δ) Connection. The current of Line 1 can be found by determining the vector difference between I R and I B and we can do that by increasing the I B Vector in reverse, so that, I R and I B makes a parallelogram.
