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, 2.5 amps; three-phase 1.443 amps.
To convert from kilowatts (kW) to amps in a 3-phase system, you can use the formula: Amps = (kW × 1000) / (√3 × volts). In this case, with 42 kW and a voltage of 120208 V, the amperage would be around 139 amps.
To convert amps to kilowatt-hours (kWh) for a three-phase system, you need to know the voltage. The formula for three-phase power is: Power (kW) = sqrt(3) x Voltage (V) x Current (A) x Power Factor. Once you have the kW, you can convert to kWh by multiplying by the number of hours the equipment operates.
Whenever we specify voltages and currents in a three-phase system, unless otherwise stated, we always refer to line values. 'Lines' (or 'line conductors') are those conductors that connect a three-phase supply to its load.So the '400 A' and '380 V' quoted in the question are line values (as opposed to phase values).The equation for the power of a three-phase load is given by:P = 1.732 x line voltage x line current x power factorSince, in your question, you make no mention of power factor, we shall assume that the power factor is unity (i.e. the load is purely resistive) and, so:P = 1.732 x 380 x 400 x 1 = 262 272 W (or 262 kW)
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.
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.
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.
