Understanding the Working Principle of Transformers in Electrical Engineering

💡 Transformers work by creating a magnetic field with electricity.

🔌 Transformers can only operate using AC, or alternating current.

🔄 When an AC generator is connected to a closed loop of cable, the current will flow in a forward and backward direction, rotating with the generator.

🔌 When an AC current flows through a cable, it creates a magnetic field that changes direction.

🔄 Multiple cables and coils can be used to create a stronger magnetic field.

💡 The magnetic field can induce a current in a nearby coil, allowing for the transfer of energy.

🔌 The change in the intensity and direction of the magnetic field induces a continuous flow of electrons in the secondary coil, creating an electric force known as EMF.

⚡ EMF is only produced briefly when the primary circuit is open or closed, or when there is a change in voltage.

🔄 To maximize the magnetic field, engineers place a core made of magnetic materials, such as iron, between the primary and secondary coils.

🔌 Transformers increase or decrease voltage using different numbers of turns in the secondary coil.

💡 Using an iron core and laminated sheets reduces energy losses in transformers.

⚡️ The phenomenon of eddy currents causes heating in transformers, which is minimized by using laminated sheets.

⚡️ Transformers are used to increase or decrease voltage and current in power transmission.

🏢 Transformers are commonly used in commercial buildings and power stations.

🔌 Transformers can be built as separate units or as one large unit with a common iron core.

Transformers have isolated coils that allow the magnetic field to pass through.

The most commonly used configuration for connecting coils is the Delta-Wye configuration.

The primary side carries the wire in a Delta configuration, and the secondary side carries the wire in a Wye configuration.
