How I can convert 220 V 3 Phase to 380 V 3 Phase
Saudi Arabia uses both 127 V and 220 V, although the 220 V is more commonly used.
You need a 110 v to 220 v transformer, which will be inexpensive for supplying an alarm clock. That steps up the 110 v suppy into 220 v for the clock.
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.
There is insufficient information in the question to answer it. You need to specify something else, such as the resistance of the load.
You cannot have 380 V between 'phases'. You can, on the other hand, have 380 V 'between lines'! '380 V between lines' refers to the voltage measured between any pair of line conductors in a three-phase system.
380
You need to know the amperage to size the wire. For 220 V at 20 A you would need 12 AWG. At 220 V at 30 A 10 AWG.
A transformer is needed to convert 110 v to 220 v or vice versa. This type of transformer is commonly used in Europe for power tools in the building trade which run from a portable 110 v transformer with a centre-tapped earth for safety so that each side is only 55 v to earth. A 3 kVA transformer for this purpose costs about £80.
it's 220 V
1- connect stablizer first to power 2- connect ups to stablizer output 220 v but be sure output v = 220 v not more the answer is yes you can
In the U.S. and Canada: 120 V. In U.K. and Europe: 220 V. Elsewhere it will typically be either 120 V or 220 V, but other voltages are sometimes used.
