Important Terminologies
- Transformer: A device that transfers electrical energy between two or more circuits through electromagnetic induction.
- Core: The magnetic core of a transformer is typically made of laminated steel sheets and which provide a low-reluctance path for the magnetic flux generated by the primary winding.
- Primary Winding: The input winding receives the electrical energy and generates a magnetic field.
- Secondary Winding: The output winding where the induced voltage is collected and delivered to the load.
- Turns Ratio: The ratio of the number of turns in the primary winding to the number of turns in the secondary winding and determining voltage transformation.
- Voltage Ratio: The ratio of the primary voltage to the secondary voltage.
- Frequency: The rate at which alternating current changes direction in a circuit usually measured in hertz .
- Step-Up Transformer: Increases the input voltage to a higher output voltage.
- Step-Down Transformer: Decreases the input voltage to a lower output voltage.
- Load: The device or system connected to the secondary winding that consumes the transformed electrical energy.
Power Transformers
Power transformers are essential devices in the electrical system that play a critical role in transmitting electricity from power plants to distribution networks and end-users This comprehensive guide provides an in-depth overview of power transformers, covering their primary terminologies, working principles, step-by-step design considerations, and practical examples.
