The watt meter on three phase system is the same as the one on your house except that it monitors all three phases at once. The meter base is called a 7 jaw base which monitors the three phases and the neutral. The house meter is a 5 jaw meter. The watt meter is a totalizer which keeps track to the watts consumed by the dials on the face of the meter, which gets read monthly by the power supplier.
Single phase formula for you to use kW = I x E x pf/1000. Three phase kW = I x E x 1.73 x pf/1000. pf = power factor. Use .9 for pf and the answer will be close.
You can't. Knowing the FLA and kV allows you to calculate the KVA; to calculate kW, you need the power factor as well.
Watts = volt x amps x 1.73
Single-phase, 2.5 amps; three-phase 1.443 amps.
To answer this question the motor's voltage must be stated and whether the supply voltage is single phase or three phase.
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).
A 'watt' is the SI unit of measurement for power, whereas the 'British Thermal Unit' (BTU) is the Imperial unit of measurement for energy. Power and energy are two different quantities, so you cannot convert watts into BTUs. (Besides, who would use a BTU these days?)
Over all losses are less in three phase AC system compared to 1 phase. For a given load (KW) 1 phase system would draw more current
Single-phase, 2.5 amps; three-phase 1.443 amps.
The formulas you are looking for are, single phase kW = I x E x pf/1000. For three phase kW = I x E x 1.73 x pf/1000.
No, it is not possible to convert a 2.4 kw single phase appliance to a 9kw 3 phase appliance. Single phase can not be converted to three phase with out considerable cost involved.

Virtually nothing. The only real benefit you would get is if you had three phase vs. single phase fans, and I'm fairly certain even the three phase convection ovens use single phase fans. The oven will be rated at a certain kW usage, which applies whether it's three phase or single phase (...and will be ~ the same). If the three phase convection oven kW usage is slightly lower, it is because it is heating slightly less (so its' kW rating is actually less than the single phase), and vice versa. Insulating factors will have a significantly higher impact on cost savings compared to single vs. three phase in this instance.
The formula you are looking for is kW = I x E x pf/1000 for single phase and kW = I x E x 1.73 x pf/1000 for three phase.
A 7.5 kW three phase load will be balanced by the manufacturer. When connected to a three phase source the line current on each phase will be equal.
To answer this question the motor's voltage must be stated and whether the supply voltage is single phase or three phase.
Use the following equation, kW = Amps x Volts x 1.73 x pf/1000.
Yes this size motor can be operated by bringing a 600 volt three phase supply to it.
A kw (kilowatt) is 1000 amps x volts. If you assume your one phase system has 120 volts, then divide by 120. Cheap, but close enough for most work, assume 100 volts, then each amp is a tenth of a kilowatt.
