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
Safety instructions . The UPS operates with mains, battery or bypass power. It contains components that carry high currents and voltages. The properly installed enclosure is earthed and IP20 rated against
Now, if you look at the “1,000 ÷ 1.732V” portion of this equation, you can see that by inserting the respective 3-phase voltage for “V” and multiplying it by 1.732, you can then divide that resulting quantity into “1,000” to get a specific number (or constant) you can use to multiply “kW” to get the current draw of that 3-phase

Dual Power regulator +12V/-12V using 7812, 7912. 24V 2A supply circuit Diagram. 18V DC voltage regulator using 7818. 5V Low Dropout Regulator Circuit using transistor and LED Make 5V low dropout regulator circuit using transistor and LED lowest voltage input is 6V so across it is 1V only, make output is 5V 0.5A.

Aside from the fact that the first equation should show Vpp for the 2nd and 3rd “Vp” as: Vp=1/2 * Vpp = 0.5 * Vpp, for completeness and clarity the 2nd formula which shows that Vp is: 1.414 * RMS, it should be shown that the RMS voltage is approximately equal to 0.7071 * Vp, and in the 3rd equation it should be shown that the average voltage is approximately 0.637 * Vp.

The good thing is that you can get a 230V single phase supply from a three phase meter load points. All you need is only a one phase wire and a neutral. If you need three-phase 400V, All the three lines and neutral (optional) are needed to run the 3-phase circuits such as 3-Φ, induction motors etc.
For Single phase 230v any of your phase i.e. Gray Black Brown and neutral = Single phase 230v However to derive Single phase 400v = connecting gray and black without the neutral to the Load This is still single phase because one of the cable is acting as neutral i.e. a return path back to the substation I hope this helps.
Single phase is a phase related to the neutral. In Belgium that's 230V. But when you have three phases you can use them in relationship with the other phases, and then the voltage between phases is 400V (230V \$\times\$ \$\sqrt{3}\$). Even at three phase you can use the 230V. You'll have 3 times the power available. That's called a star Subscribe to my channel: http://bit.ly/2rYtS79I'm no way an expert at electronics.
