Classification of transformer:
Single Phase Transformer:
Use of single phase transformer:
A single-phase transformer is commonly used in a variety of applications, particularly in residential and light commercial settings. Here are some common uses:
Power Distribution: Single-phase transformers are used to convert high voltage electricity from the distribution network to a lower voltage 240V or 120V suitable for residential use.
Residential Appliances: These are often found in power supplies for household appliances, such as refrigerators, air conditioners, and washing machines, where single-phase power is sufficient.
Lighting Circuits: Used in lighting circuits to supply the voltage required for lamps and fixtures in homes and small businesses.
Industrial Applications: In small industrial settings, single-phase transformers can be used in power equipment that does not require three-phase power.
Battery chargers: These are employed in battery charging applications, converting AC to suitable DC voltage.
Isolation: Single-phase transformers can provide electrical isolation for sensitive devices, protecting them from voltage spikes and surges.
Signal Transmission: These are used in audio and communication systems to match impedance and isolate different layers of circuitry.
Three Phase Transformer:
Use of Three phase transformer:
1. Transformers are used to convert low voltage to high voltage as required in transmission of electrical power over long distances.
2.Transformers are used to convert the higher voltage of the transmission line to lower voltage as required.
3. With the help of transformer in the distribution line, the voltage can be reduced to the required value of the consumers.
4. Transformers are used in various machinery and necessary testing of electrical, electronics and computer engineering.
5. Transformers are used in electrical communication circuits.
6. Transformers are used in radios, televisions, tape recorders, etc.
7. Instrument transformers are used for various measuring devices and protection devices used in electrical circuits.
