How many BTU does kW electric heater put out running at three phase 465 volts?

Not enough information. You didn't specify the amount of kW - and you really can't calculate that, just from the volts. Once you know the amount of kW (which is a unit of power), you still need to multiply by time to get energy. Then you can do the appropriate conversion to BTU, which is also an energy unit.

What is the running amps of a 45 kW motor?
To answer this question the motor's voltage must be stated and whether the supply voltage is single phase or three phase.
Why would three phase be used instead of single phase?
Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.
How do you use a one phase motor in place of a three phase motor?
To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
When you have 56KVA available in 3 phase supply how much is your available current in 3 phase and how much in 1 phase?
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).
Where are three phase transformer systems used?
Any where that a three phase supply distribution is needed to operate three phase equipment.
Does a two phase heater need a two phase thermostat?
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.
If I use a three phase electric ac and heater is it more economical that using a 3 phase gas ac and heater?
Well, as far as I know, there is no 'gas' A/C. The A/C will be electric, regardless of the type of heat used. Whether electric heat or gas heat would be more economical is really dependent on your electric and gas utility rates and the efficiency of the appliances involved.
Do you need a neutral to install 480 volts 3 phase heater?
If the heater is rated as a 3 phase 480 volt heater then a neutral is not needed. If the voltage stated is 277 volts three phase then a neutral is needed.
Is 380 volts electric motor a single phase or 3 Phase?
It is probably a three phase 50 Hz motor.
Can a 240 volt single phase load connect between the high leg and regular phase leg of delta connected three phase system?
yes but voltage will be out a little.This ok for something like a heater which wont care.But for an electric motor starting and overheating maybe a problem.In the US this would be 220v single phase and 208 volts 3 phase.
Is three phase induction motor continue running when any of the two phase is disconnected?
This question doesn't really make any sense - any of the two phase? A three phase induction motor requires 3 phases to start - if a single phase is lost while the motor is already running then yes the motor will continue to run. A three phase motor will not start if it is missing a phase.
Single phase to three phase conveter for driving three phase motor using single phase?
This inverter is the cheapest and always available from famous vendors like ROCKWELL ,ABB, SIEMENS ,SCHNEIDER ELECTRIC....etc .
What are the applications of three phase to single phase electric power distribution systems?
All high-voltage distribution systems are three-phase. Single-phase 'spurs' off the main line, supplying, for example, farm houses, are simply two lines of a three-phase system.
Reverse running of three phase meter?
The reverse running of a three phase meter is possible when one of the meter's two potential coils fails. This is a problem found typically on a Delta service. A three phase meter in this condition is damaged and will report lower energy use than actual.
Do you change the high leg if your three phase motor is running in reverse?
yes
What is circuit breaker rating when electric load of a machine is 11.5 kW?
This question cannot be answered as asked. you would need to know also the voltage and phasing. Assuming we are dealing with 120-volt, single phase, 11,500 watts would be 55-running amps. Assuming we are dealing 208-volts, three phase, 11,500 watts would be 32 running amps and assuming we are dealing with 250-volt three phase, 11,500 watts would be 26.5 running amps. I hope I have answered your question.
How many phases are in ac electric?
A.C. is generated, transmitted, and distributed as three phase.
