Transformers use electromagnetic induction to transfer energy between circuits
Transformers can increase or decrease voltage levels to meet specific requirements
The operation of a transformer is governed by Faraday's Law of electromagnetic induction
Transformers consist of two coils, the primary and secondary windings, which are wound around a magnetic core
The magnetic core, typically made of laminated silicon steel, provides a path for the magnetic flux and reduces energy losses
Transformers experience energy losses due to eddy currents and hysteresis, which can be minimized through design
Core-type transformers have windings arranged around a magnetic core and are versatile for various power applications
Shell-type transformers have windings encased within the layers of the magnetic core for high efficiency
This type of transformer uses a unique winding connection to mitigate magnetic saturation in the core
Transformers can increase or decrease voltage levels through the use of step-up and step-down configurations
The transformer turns ratio is directly proportional to the voltage transformation ratio and is essential for efficient voltage conversion
The ideal transformer model assumes no energy losses and is useful for understanding the basic principles of transformer operation
Single-phase transformers are commonly used in residential and light commercial settings
Three-phase transformers are prevalent in industrial and high-capacity electrical distribution systems
