What is a transformer used for in home?
In the case of electrical utilities in homes, they use transformers to change the voltage of electricity as it travels from the power plant to your home. First using a transformer, the voltage of electricity coming from a power plant is “stepped up” to the right level for long-distance transmission.
What is the function of electrical transformer?
A transformer is an electrical device designed and manufactured to step voltage up or step down. Electrical transformers operate on the principle of magnetic induction and have no moving parts.
Where are transformers used around the home?
Transformers are used virtually everywhere, including power generation plants, industrial factories, commercial spaces, and residential areas. They can be as tall as a multi-storey building, or even small enough to fit inside an electric toothbrush.
Why are transformers necessary for home electrical service?
When electricity is generated at a power plant, transformers boost the voltage from a few thousand up to hundreds of thousands for purposes of long-distance transmission. As these wires reach points called power substations, transformers reduce the voltage to under 10,000 volts.
Do I need a transformer at home?
If you are working at home using small power tools like drills, saws and breakers, a 3kVA transformer will most likely be sufficient. For some larger power tools or ‘continuous use’ equipment like floodlights and space heaters, you may need a larger 5kVA transformer.
What is the best function of a transformer?
The transformer is basically a voltage control device that is used widely in the distribution and transmission of alternating current power. The function of the transformer, as the name implies, is to transform alternating current energy from one voltage to another voltage.
Why are transformers needed?
Transformers help improve safety and efficiency of power systems by raising and lowering voltage levels as and when needed. They are used in a wide range of residential and industrial applications, primarily and perhaps most importantly in the distribution and regulation of power across long distances.
