How can change voltage from 440 v 3 phase to 208 v 3 phase?
I have 12 amps 208/3/60 what would the amps be @ 440/3
Why 3 phase is 440 volts why not 660?
Because 3 phase voltage is not algebraic sum it is the vectorial sum. Vijaye Raj A.I.E.M.D
What is the formula to convert 440 to 220 single phase while in motor rewinding?
If it was 440 v single-phase, use half the number of turns in the windings, but use thicker wire of double the cross-section. Or to use the same wire again, fold the wire once into half its length and use that.
Can a 440 volt single phase device be made to run on 220 volt single phase?
Not directly. You could use a 220V - 440V transformer to boost the voltage up to 440. Be sure its rated for the proper KW. Check the nameplate on the device for the KW rating. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
What is the minimum voltage of US household mains supply?
240, single phase for houses208 3 phase for comerical property, can be single phase.480 volt for industrial property or 660 volts,all 60 HzUSA calls it single phase but there is actually 2 hot leads coming into the house with a natural and a ground.It is actually two 120 volt 'hots' which are 180° out of phase from each other. Voltage between either of these and ground will be 120 V. Voltage between the two hots is 240 volts. It is single phase because it is pulled off one of the phases from 3-phase, then a center tapped transformer gives the two 'opposite phases' (ground/neutral is off the center tap)In Vietnam we have 440 volts, 3 phase, 50 Hz on the poles.They bring in one hot wire and one ground. I call this single phase,It equals 220 volts in your house.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
How do you calculate 440v phase?
Let's get the terminology correct. A 'phase voltage' is measured across a phase, whereas a line voltage is measured between two lines. So there is no such thing as a 'phase to phase' voltage -it's a line to line voltage (hence the term 'line voltage').
On a vessal On a three phase 440v supply what is the voltage on the individulal phases?
Phase voltage is equal to the line to line voltage divided by root 3 or 1.732. So 440 L-L/1.732 = 254V. Your phase voltage is 254V.
What is the mean of 220-440 connection of 3 phase motor?
Star 220 v and delta 400 i star 58 percent only voltage applied delta 400v appliedAnswerThese figures do not represent three-phase, four-wire, system voltages, because if the line voltage were to be 440 V, then the phase voltage would be 254 V; or, if the phase voltage were to be 220 V, then the line voltage would be 381 V.
Three phase voltage in india?
It is 230V single phase and 440V in 3 phase system at 50 Hz.AnswerIf the single-phase voltage is 230 V, then the three-phase voltage must be 400 V, not 440 V. The line voltage is 1.732 times the phase voltage.
How do you get single phase 440 from three phase 440?
You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.
Why 3 phase line 440 volt instead of 660volts?
common phase
How can change voltage from 440 v 3 phase to 208 v 3 phase?
I have 12 amps 208/3/60 what would the amps be @ 440/3
Why is it stated - 3 phase 440 VAC when one phase voltage is 220 VAC?
In three-phase there are three live wires and a neutral. The voltage of a three-phase system is always quoted as the live-to-live voltage, and the voltage from one live wire to neutral is 57.7% of that. A 440 v 3-ph system has 254 volts between live and neutral. <<>> The question statement is not correct. Two legs from a three phase three wire 440 volt system will still be 440 but classed a single phase. On a three phase four wire system supply, the voltages will be determined by the following equation. 440/(square root of 3) 1.73 = 254 volts. The second single phase voltage attainable from this source connection is any one of the three phase legs to grounded neutral center point. This is known as a wye or star point connected voltage supply. To obtain a 220 volt single phase voltage, the three phase system would have to have a voltage of 220 x 1.73 = 380 volts.
Why the voltage between phase to neutral is 240v compared to phase to phase is 415v?
What you are describing is a three-phase, four-wire, system having a phase voltage of 240 V and corresponding line voltage of 415 V.You do not add the three phase voltages (3 x 240 = 720 V) to obtain a line voltage.The three phase voltages are actually displaced from each other by 120 electrical degrees, so any pair of phase voltages must be vectorially-added to obtain a line voltage. If you perform this calculation, you will find that the line voltage is always 1.732 times larger than the phase voltage. So, 1.732 x 240 = 415 V.
How much voltage is there in 3 phase supply?
It depends on the electrical standards in your country. For example, in Europe, the nominal voltages for low-voltage three-phase, four-wire, distribution systems is 400 V (line-to-line) and 230 V (line-to-neutral).
Is it possible to connect 3 phase 440 V without neutral line to the machine having 3 phase 4 wires with neutral line?
yes
