only way to convert from 3 phase to 240 would be to change the electric motor on the compressor
Amperes when kva is shown. The formula is, Amps = kva x 1000/1.73 x volts.
If you have a voltage of 127 volts to neutral (ground) then your wye connected three phase leg voltages will have to be 127 x 1.73 = 220 volts. This voltage is within the 10% allowance for voltages as should operate the compressor. As the voltage is lower that specified, the amperage rating when a reading is taken will be higher than that of the equipments nameplate.
To convert 7620 volts to 240 volts, you would need to use a transformer. The transformer would step-down the voltage from 7620 volts to 240 volts. The ratio of the turns on the transformer primary and secondary windings determines the voltage transformation.
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
If you mean by a converter, a transformer, to change the voltages then yes 240 volts can be transformed with a step down transformer from 240 volts to 208 volts in a single phase system. To answer the question single phase can not be converted to three phase without additional expensive equipment. One piece of equipment that will do it is a variable frequency drive. Another piece of equipment is a roto-phase. Either of these pieces of equipment would probably cost more than the grill you are trying to supply a voltage to.
A voltage of 240 volts is not a common three phase voltage. Single phase kva of 240 voltas and 50 amps is I x E/1000 = 240 x 50 = 12000/1000 = 12 kVa -- Assuming the 240 volts is phase to phase voltage, and this is a three phase application: KVA = V*I*sqrt (3) = 20.78KVA
These voltages are both wye connection three phase voltages. The voltage difference comes from the primary three phase voltage supplies. 277 volts is obtained from 277 x 1.73 = 480 and 240 volts is obtained from 240 x 1.73 = 415. 480/277 volts is a common three phase American voltage. 415/240 volts is a European voltage. In Canada a common three phase voltage is 347/600. The 240 volts could also be a single phase voltage in North America derived from a split phase secondary on a distribution transformer that supplies 120/240 volts to homes.
Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.
You would need to use a voltage transformer or converter to step down the voltage from 415 volts to 240 volts. Make sure to select a transformer that is rated for the appropriate power capacity and input/output voltage requirements to safely convert the voltage.
A three phase four wire commercial distribution service will not give you 240 volts. The nearest voltage you can get is 208 volts. It is a wye connection which gives you 208 volts between the three legs and 120 volt between any of the three legs and ground. This ground point is the systems neutral point.
No, it is not recommended to convert a Yamaha Clavinova from 120 volts to 240 volts. This could damage the instrument and void any warranty it may have. It is best to purchase a Yamaha Clavinova that is already rated for 240 volts if needed.
126 volts sounds very close to a standard home voltage of 120 volts, which is single phase. 208v is a three phase voltage, and is the lowest I have seen. 240 is single phase (usually center tapped, so in your house you have +120, and -120 referenced to the neutral which provides the normal 240 for dryers, stoves, etc.).
