Connect a 2:1 ratio step-down transformer across any two line conductors of the three-phase supply, and the secondary will provide a 240-V single-phase supply. Unless you are qualified to do so, don't do this yourself, because the circuit will require the installation of overcurrent protection devices such as fuses or circuit breakers, in accordance with the relevant regulations, to make the installation safe.

What is the amperege of single phase and 3 phase 1kW motor operating at 230 volts single phase and 415 Volts 3 phase?
To answer your question properly, you need to know the input power to these machines, whereas you are specifying their output powers. In other words, you really need to know their efficiencies in order to determine their input powers.Once you have figured out their input powers, then you need to divide the power by the supply voltage in the case of the single-phase motor, and the power divided by 1.732 times the supply voltage in the case of the three-phase motor.Incidentally, your motors' specs should either be 230/400 V or 240/415 V, NOT 230/415 V.
How to convert 100ampere to kva?
Divide by your number of phases 1 or 3 then divide by your Voltage. If its a 3 phase supply Voltage you need to divide by your 3 phase voltage for balanced loads and by your single phase voltage for unbalanced loads requiring a neutral.
Can you re wire a 3 phase panal to single phase?
You can't in any simple way. You must have three phase electrical supply from the local power company to install a three phase panel and employ three phase power. Virtually all residences in the U.S. have single phase power supply only. (Even if you have 220/240 V service that's still single phase.) The primary advantage to three phase power is it's ability to run electric motors more efficiently and provide them a longer life. That's why it's only supplied to commercial properties. If you need three phase power from a single phase panel then that can be done. It is said money can make anything happen. Depending on the amount of money you want to spend to make this happen there is a device on the market called a VFD ( Variable Frequency Drive). On the three phase input terminals you apply your single phase voltage. On the output terminals you connect your three phase motor. When run in this configuration there is an internal switch that has to be changed to let the VFD know that it should be looking for only two lines on the input to be hot. Other wise the VFD thinks that there is a line loss on the three phase input terminals and the unit will not start.
Do they make 3 phase oven for home use?
Three phase ovens are made for home use. It is important however to know if the home is wired for three phase or for single phase.
How do you get 480v 3 phase from 220v single phase?
Buy either a phase convertor or motor-generator with the proper input and output ratings. Essentially you have to generate your own 3-phase power using the 220V as the energy input. There is no wiring or connection scheme that will directly do this.

Can you convert a 3 phase convection oven to single phase?
I dont know if you can actually convert the oven's wiring from 3-phase to single phase. You can, however, convert the single phase circuit that will feed the oven to a 3-phase system. To this you will need a phase converter. Now, where to purchase such an item, and how much they cost? i have no idea.
How many watts is 4.75 amp refrigerator starting watts?
To convert amperage to watts, you need to know the voltage, power factor, and the number of phases that you are working with. For a residential refrigerator this is single phase, an industrial refrigerator could be three phase.
How to convert 100ampere to kva?
Divide by your number of phases 1 or 3 then divide by your Voltage. If its a 3 phase supply Voltage you need to divide by your 3 phase voltage for balanced loads and by your single phase voltage for unbalanced loads requiring a neutral.
How do you calculate amp draw if you have 1 phase volts and kw?
For a single phase supply: you need to know the volts, kW and the power factor. If the power factor is unknown, assume 0.75, except for heating elements which have a power factor of 1. Multiply the kW number by 1000 then divide by the voltage. The answer should be divided by the power factor to find the current in amps.
How many amps will a 3 phase 380 volt 11Kw motor draw?
In order to answer this question, you need to know (a) its efficiency, and (b) its power factor at full load. 11 kW (not 'Kw') is its output power, so you need to know its efficiency in order to determine its input power. Then, because, for a three-phase system, power is equal to 1.732 times the product of the line voltage, line current, and power factor, you also need to know its power factor.
How do you calculate absorbed power for motors?
we can calculate power consumption of motor by multiplying voltage and current which motor is take.AnswerYou need to know its rated power (i.e. its output power) and its full-load efficiency, from which you can calculate its input power.
How do you know if the single line is single phase or 3 phase?
If the single line is compared to another single line and the voltage that you need is correct then you are looking as a singly phase supply. The electrical classification of single phase is that any two legs of a three phase supply can be called single phase. Look on the nameplate of the distribution panel. There it will state what the panel is, either single phase or three phase. Look at where the distribution enters the building from the utility supply. If there are three insulated conductors (red, black and blue) wrapped around a bare aluminium messenger wire it is a three phase wye connection service. If you see two black insulated conductors wrapped around a bare aluminium messenger it is a single phase service.

How do you calculate kvar of capacitor bank if you know only the kw?
Your question is rather vague. Are you asking how do you determine the reactive power of a capacitor bank necessary to improve the power factor of a load (in which case, is it a single-phase or a three-phase load), or are you asking how to convert a capacitor bank's capacitance into reactive power?If the former, then you need to know the reactive power of the load before power factor-improvement, and the resulting reactive power after power-factor improvement, and the difference between these two will tell you how much reactive power you need to add in the form of capacitors.
How do you rewire 3 phase hot water system to single phase power?
It could be a problem because if it's a 3-phase system it might be an exceptionally powerful water heater. See an electrician who will know what questions to ask once he has seen the probem.
