Until the requirement for the UK to conform to EU standards, the standard low-voltage three-phase nominal line voltage was 415 V (+/- 6%). After the adoption of this EU requirement, the nominal line voltage became 400 V (+10%/-6%).

What is voltage phase to phase 380 3 phase?
let me clear difference between phase voltage and line voltage. phase voltage is measure line to neutral and line voltage is measure line to line.there is correct answer that 380 volt is sum of multiply of square root 3 to phase voltage 220 volt.phase volt line volt220 volt x 1.732 = 381 volt230 volt x 1.732 = 400 volt240 volt x 1.732 = 415 voltM.

What is the phase current of a three phase 2.2kw 415v motor connected in star?
The line current would be the same if the motor were connected in delta. The current can be based on the rule of thumb which says 7 amps must be allowed for a 1-HP single-phase motor on 240 v. A 2.2 kW motor is three times as powerful, and on a three-phase supply of the same voltage (240/415) it would draw 7 amps.
What is cable size for a 7.5kw 3 phase induction motor 70 meter run for cable 415v?
Current is about 18 amps per phase. Allowing for power factor and startup, I'd size the wire for 40 amps per phase, which is #5 wire. This wire has a resistance of 0.39 ohm per 1000 ft, which is 0.39 ohms per 305 meter, or 0.09 ohms per 70 meter. At 40 amps, there is a voltage drop on the wire of 40*.09 or 3.6 volts, less than 1% loss, so that is OK. Use 4 conductor #5 copper wire insulated for 480 volts. <<>> A #12 copper conductor will limit the voltage drop to 3% or less when supplying 13 amps for 230 feet on a 415 volt system.
What is the amps for 6000 watts 415 volts 3 phase heater?
There are zero amps in a 6kW 3 phase heater. Amperage is the result of dividing the Watts by the Voltage. A = W/E. Without stating the voltage the heater operates on the amperage can not be calculated.
Can 3 phase 380 volts 50 hz motor run on 440 volts 50 hz supply?
No, the voltage gap between the two voltages is too large.
What is the voltage for a single phase from a 415 volt 3 phase and neutral supply?
240V. 415 / 1.73 = 240

Acceptable voltage drop for 3 phase 415 volt motor?
The voltage drop should not exceed 3% on a feeder or branch circuit.
How many amps will a 3 phase 415 volt 12 kw heater draw?
100 KW divided by 415 volts is 241 amperes. Power = voltage times current, so current = power divided by voltage.
How do you convert 415 volts to 240 volt?
415 V is the 'line voltage', and 240 V is the 'phase voltage' of a 415/240-V three-phase, four-wire, system. These were the standard nominal voltages used in the UK before EU 'harmonisation' forced them to be 'renamed' (but not actually changed) to '400/230 V'!! So there really isn't such a thing as separate '415-V' and '240-V' three-phase systems. And there is no economic way of changing the supply frequency to a different frequency. Incidentally, the symbol for 'hertz' is 'Hz', not 'htz'.
What thickness cable require for 415 volt?
Voltage determines a cable's insulation thickness, not its conductor thickness (or, more accurately, its cross-sectional area). It's current that determines the csa of a conductor, not voltage.
What is percent of power loss at 415 volts against 11000 volts?
Power = voltage times current, and the power loss is the loss in the line, I^2 * R. At 11,000 volts, the current will be (11,000 / 415 = ) 3.77% of what it is at 415 volts. So the power loss in the line at 11,000 volts will be (3.77% ^2 = ) .14% of what it is at 415 volts.
How do you calculate hp to amps in 3 phase suply 415 volt?
One horsepower electric is 746 watts. Divide that by 415 to get amps, giving about 1.8. Divide that further by 3 because it is three phase power, giving about 0.6. Divide that further by power factor to compensate for apparent versus true power caused by reactance, say about 0.8, giving about 0.75.
What are the volts per phase on a 240 volt system?
By 'volts per phase', I assume you mean 'phase voltage' as opposed to 'line voltage'?It depends on the country in which you live. In North America, for example, the secondary output of a three-phase distribution transformer typically delta connected, 240 V corresponds to both the phase and line voltages.In other countries, where a three-phase distribution transformer's secondary is wye connected, 240 V is typically a phase voltage and 415 V is a line voltage.
How can a step down transformer which is transforming 450 volt in the last tap be changed to 415 volt?
The instruction for changing the taps on a transformer can be found on the transformers nameplate. These taps will be on the primary side of the transformer. Each tap position will state what the voltage will be on the output when the individual tap is selected.
What does 3 phase voltage measure in Australia?
415 volts
When computing watts to amps for 3 phase should the voltage input be 240 or 415v?
The equation for power in a balanced three-phase system is given by:P =1.732 EL IL x (power factor)WhereEL = line voltageIL = line currentIn your example, 415 V is a line voltage.
