You have two devices that are rated at 230 VAC single ph and your supply voltage is 480 VAC 3 ph you need a 480 VAC 3 phase to 230 VAC three phase xfrmer how do you calculate the xfrmer size?

The transformer size is calculated by using the load current that is required on the secondary side of the transformer. This secondary current is multiplied by the secondary voltage times 1.73. This total is then divided by 1000 to give you KVA. KVA = I x E x 1.73/1000.

Why would a generator put out 240 volt single phase?
For a home generator, to supply voltage for devices that require 220 V or 240 V. An electric oven or clothes dryer are examples of such devices. The generator at the power plant actually generates electricity at a much higher voltage, for easier transmission (and those are 3-phase generators). Also most homes run on 240 single phase. Power is split at the breaker box. To supply 120 loads and 240 loads. 240 single phase is a common voltage.
How do you calculate amp draw if you have a 25KW strip heater?
Divide 25,000 by the supply voltage to get the current.
Which laser printer component converts AC line voltage into the DC voltages the printer can use?
As in all electronics devices that obtain power from the AC electric system, a power supply converts the AC to the DC voltage(s) needed by the electronics in the device. Depending on the needs of the device this power supply may deliver a single DC voltage or as many as several dozen different DC voltages.
What are advantages power supply in computer?
The power supply converts the high voltage (e.g. 120VAC in US, 240VAC in Europe) alternating current house electricity supply down to the various different low voltage direct current supplies needed by different devices that make up the computer. These low voltage direct current supplies are tightly regulated in the power supply circuitry to prevent transients in the house electric supply from perturbing the computer's electronics as well as to compensate for variations in power demand as the different devices that make up the computer operate.
Methods of calculating Ripple voltage in supply without using oscilloscope?
Measure AC voltage with multimeter. It is easiest way to check how big ripple is. There is no way to 'calculate' value.
What is the voltage and current for a single phase supply?
240v

What is typical single phase voltage in Canada?
The standard nominal voltage in Canada for a single-phase residential supply is 240/120-V split-phase supply.
How do you calculate weight of PVC insulation on cables?
By multiply current supply and voltage
What size wire 100 kva transformer?
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
How do you calculate amp draw if you have a 25KW strip heater?
Divide 25,000 by the supply voltage to get the current.
HOW and Why there is 440v supply in three phase and 230v supply in single phase?
because all over the world there is an standard rate of voltage

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.
Which calble use single 1 hp motor?
Motors with same horse-powers have different full load amps when operating. To calculate the size of wire to supply the motor feeder the voltage or current of the motor has to be known.
What is resistor function?
In an electronic circuit power supply voltage is generally fixed. Resistors is a current limiter for correct devices polarization.
