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.
What is the ratio of a 480vac single phase and a 120 vac secondary voltage?
The ratio for a 480 VAC to 120 VAC is 4 to 1.

What is the difference of VAC to Voltage?
Voltage is a general term. VAC & VDC are specific terms.
What can happen if you use a 440 vac capacitor instead of a 370 vac?
You can always use a higher voltage rated capacitor, it will probably just last a little longer.
How do you convert 24 vac to 5 vac?
