Types of Transformer

  • Step-Up Transformer
  • Step-Down Transformer
  • Isolation Transformer

Step-Up Transformer

Equation:

Advantages:

  • Transmit electricity over long distances at low cost.
  • Helps in reducing the resistance on the line.
  • Ability to work continuously.

Limitation:

Step-Down Transformer

Equation:

Advantages:

  • Easy power transmission at low cost.
  • Highly reliable and efficient.
  • Provides varied voltage requirements.

Limitation:

Isolation Transformer

Equation: ​

Advantages:​

  • Provide safety to electronic components and the persons against electrical shock.
  • Suppress the electrical noise.
  • Avoids ground loops.

Limitation:

  • Air-Core Transformer
  • Iron Core Transformer
  • Ferrite Core Transformer

Air-Core Transformer

  • Zero distortion.
  • Zero dissipation of signal quality.
  • Noise-free operation.

Limitation:

Iron Core Transformer

Ferrite Core Transformer

  • Low reluctance magnetic path.
  • High current resistivity.
  • Provides low eddy current losses over many frequencies.

Limitation:

  • Power Transformers
  • Distribution Transformers

Power Transformers

Advantages:

  • Suitable for high voltage applications (greater than 33KV).
  • High insulation level.
  • Minimize the power loss.

Limitation:

90% OFF — Power System Protection Fundamentals

Distribution Transformers

  • Single-phase transformer
  • Three-phase transformer

Single Phase Transformer

Advantages:

  • Simple network.
  • Cost effective.
  • Most efficient AC power supply for up to 1000 watts.

Limitations:

Three Phase Transformer

Advantages:

  • Large motors or heavy loads materials.
  • Transmission of power to long distance through magnetic field.
  • Maximum power transfer capability.

Limitations:

  • Indoor Transformers
  • Outdoor Transformers

Indoor Transformers

Advantages:

  • Low maintenance cost.
  • Safer option as compare to oil-filled transformer.

Limitations:

Outdoor Transformers

Advantages:

  • Smaller and more efficient.
  • Lower operational costs.

Limitations:
