Yes, you can obtain 120V single-phase power from a 440V three-phase system using a transformer. By using a step-down transformer that reduces the voltage from 440V to 120V, you can safely access single-phase power. It's important to ensure that the transformer is correctly rated for the load and that all safety regulations are followed during installation. Always consult with a qualified electrician for any electrical work.
A 24v transformer converts 120v to a lower voltage for use in push buttons, like doorbells, thermostats, gas valves, or air conditioning systems. They are an essential tool for electricians.
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
Use a step down transformer 240 primary to 120 secondary. You must know what the connected load (amps) is so that you don't overload the transformer. Small transformers are rated in VA.
Count the turns ratio of the windings. The voltage ratio is equal to the turns ratio. The current ratio is equal to the inverse of the turns ratio. For instance, a power transformer with a 10:1 turn ratio (primary to secondary) running on 120V will produce 12V. If it consumes 1 ampere from the input, it will provide 10 amperes to the output.
This type of a transformer is known as a step up transformer.
The ratio of AC voltages is the same as the ratio of winding-turns in the transformer. Vp / Vs = Np / Ns (10 volts AC) / Vs = 200 / 20 = 10 Vs = (10 volts AC) / 10 = 1 volt AC.
You can use a step-up transformer. Transformers are rated in primary voltage, secondary voltage, kVA, phases (single and three) and other parameters then equipped with indoor and outdoor enclosures. Be sure to consult a professional engineer or electrician when choosing and installing a step-up transformer. There are several NEC issues involved as well as choosing a transformer that is right for the type of load you have. One without the proper licensing AND knowledge of transformer circuits should never install 480V wiring or transformers.
120v
Please go to discuss question page.
120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V

You can use a transformer or voltage converter to step up the voltage from 120V to 205V for your equipment. Make sure to select a transformer that can handle the wattage and current requirements of your equipment to avoid damaging it.
Depends on what the voltage is being stepped down in that particular control transformer. Control transformers usually step down a voltage of 480/208v to 120V. The 120Volts can now be used in safer manner to "control" start/stop buttons, and other components that are only built to run on 120V
to derive 120 volts from 480 volts you have to use a transformer, based on your needs. If you needed 100 amps at 120 volt single phase you would need a 12kva transformer. This is just an example.
