A service transformer is a type of transformer used to step down the voltage from the distribution level to a lower voltage suitable for residential or commercial use. It is typically installed at the point where electricity enters a building or facility, providing stable and safe voltage for electrical systems and equipment.
A transformer is an electrical device that transfers electrical energy between two or more circuits by electromagnetic induction.
It is used to change the voltage level in an AC (alternating current) system, either by raising or lowering the voltage to meet the needs of electrical equipment or to transmit power efficiently over long distances.
Types of transformers include:
- Power transformers: used in high voltage transmission and distribution networks to increase or decrease voltage.
- Distribution Transformers: Used to distribute electricity at lower voltages to end users.
- Isolation transformers: provide electrical isolation between circuits while maintaining the same voltage level.
- Autotransformers: Use a single winding to provide voltage transformation with a variable transformation ratio.
- Instrument transformers: Include current transformers (CT) and voltage transformers (VT) for measurement and protection purposes.
- Three-phase transformers: Used in three-phase electrical systems to provide balanced power distribution.
A transformer is an electrical device used to change voltage levels in an alternating circuit through electromagnetic induction.
The transformation ratio of a transformer is the ratio between the primary voltage and the secondary voltage, determined by the ratio between the number of turns of the primary winding and the number of turns of the secondary winding. This ratio dictates how the voltage is increased or decreased.
A “people transformer” is not a standard term in electrical engineering. It may refer to a concept or device that is little recognized in the field. If the term is used in a specific context or industry, it may require clarification or more context to understand its meaning accurately.
