How do you convert 3phase connection to 2 phase?
Any two legs of a three phase system can be classed as a single phase supply.Alternative AnswerAs the above answer points out, connecting a load between any two line conductors of a three-phase supply will give you a single-phase load. But you must, of course, take into account the voltage rating of the load you wish to connect.In Europe, three-phase low-voltage distribution is normally by means of a four-wire system, comprising three line conductors and a neutral conductor, operating at 400 V (line-to-line) and 230 V (line-to-neutral).Your single-phase load's voltage rating must, of course, match either the single-phase supply's line-to-line or line-to-neutral voltages. In Europe, most single-phase loads are rated at 230 V so, for a residential three-phase, four-wire system, it is usual to obtain a single-phase supply by connecting the load between any one of the line conductors and the neutral conductor.But, if you have a non-standard, 400-V single-phase load, then connecting that load between any two line conductors will also give you a single-phase supply.
How can you get 3 phase supply from single phase supply by using only transformers?
You cannot. By definition, the potential of each line must be displaced from each other by 120 electrical degrees, and this is only achievable from a three-phase source.
Why delta connection is used in load side?
There are a number of advantages why three phase (delta or Y configuration) is preferred over single phase circuit. The best advantage is that the each of the three lines in a three phase circuit can act as single phase thus effectively getting three single phase circuits in one transmission. Another advantage is whether it's single phase or three phase, the generation is the same, therefore three phase has more practical value. Also, the instantaneous power in single phase falls to zero but in three phase system, the net power from all the phases is continuous.
Is the voltage rating on a light bulb the rms value or peak value?
It's the RMS value. A 120 volt lamp (light bulb) is rated according to its RMS voltage. Just like appliances in the home are rated at 120 volts (like your fridge, microwave and toaster), or 220 volts (like your clothes dryer). Note that these appliances will have to stand up to the peak voltage on the AC line. Naturally. And the peak voltage on an AC line is 1.414 times the RMS value of voltage. That means in a 120 volt AC line (120 volts RMS), the peak value of the voltage will be 1.414 times the 120 volts, or right at about 170 voltspeak for each cycle.
How do you convert 230v to 208 volts single phase?
A source of 208 volts can be obtained from any two legs of a three phase four wire 208 volt system. The two legs are classed as single phase 208 volts. The lead tags can be L1-L2, L2-L3, or L3-L1 all of which will give you 208 volts. Any of these lead tags to the grounded star point (wye) will give you 120 volts.
How do you draw lines of symmetry lines in a regular hexagon?
From each vertex to its opposite vertex. These will be centered on a shared point at the center of the hexagon. Each complete line will be a line of symmetry for the hexagon.
What does 120 eighty character lines of text mean?

Which pair of lines are examples of lines of longitude Prime meridian and 120 degree E International date line and 60 degree N?
The first pair is.
What is the difference between single pole and double pole thermostats?
A line thermostat on a 240 volt heater must open both of the supply lines that feed the heater. This is where the double pole thermostat is used. On 120 volt heaters only one hot line needs to be opened to shut the supply off from the source therefore a single pole thermostat is used.
How do you convert 120 into a decimal?
120 into decimal = 120.0
How do you convert 120 kilo to pounds using Microsoft Excel?

How many lines of symmetry does a dodecahedron have?
120.A regular Dodecahedron has 120 symmetries.
What is an AC single phase 2 wire system?
two wires coming off the secondary of the transformer ex. residential voltage of 120 volts each line, and one neutral wire, L1 to neutral is 120 volts, L2 to neutral is 120 volts, L1 to L2 is 240 volts.AnswerA single-phase, two-wire, system comprises a line conductor and a neutral conductor. In European countries, the line conductor for a residential supply is at a nominal potential of 230 V with respect to the neutral.In North America, a 'split phase' system is used for residential supplies; this is a single-phase, three-wire, system comprising two line conductors which and a neutral conductor. The nominal potential difference between the line conductor is 240 V, while the potential of each line conductor with respect to the neutral is 120 V.
What is the largest single factor of 120?
The largest single factor of any positive number is the number itself.
How do you get line voltage from a single phase 3 wire system?
Answer for USA, Canada and countries running a 60 Hz supply service.A three wire system uses two lines L1 and L2 and a Neutral. You can obtain a 120 volt potential from L1 to N or 120 volt potential from L2 to N. Between L1 and L2 you can obtain a potential of 240 volts.
