types of transformer

There are various types of transformer, each with its own applicable usage. In this blog we will give you an overview of Transformer, their Working Principle, types of Transformer with Equations, Advantages and Limitations. We have published this topic in detail on our Website, we recommend you to read it on AllumiaX blog Types of Transformer.

Transformer

Working Principle of Transformer

“The Rate of change of flux linkage with respect to time is directly proportional to the EMF induced in a conductor or coil”.

Faraday’s Law

E= N dϕ /dt

Types of Transformer

We just launched our Power Systems Engineering Vlog series and in this series, we are going to talk about all sorts of various power system engineering studies and commentary. We will overview the different blogs written by AllumiaX. It’s fun, it’s lively, it’s a video blog essentially and we hope that you’ll join us and benefit from it.

1. Based on Voltage Level

On the basis of voltage level, transformer types are listed below.

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

Step-Up Transformer

Equation:

  • 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:

2. Based on the Core Medium

On the basis of core medium, transformer types are listed below.

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

Air-Core Transformer

Advantages:

The three advantages of Air Core Transformer are:

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

Limitation:

Iron Core Transformer

Ferrite Core Transformer

Advantages:

The three advantages of Air Core Transformer are:

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

Limitation:

3. Based on Usage

On the basis of usage, transformer types are listed below.

  • Power Transformers
  • Distribution Transformers

Power Transformers

Advantages:

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

Limitation:

Distribution Transformers

4. Based on Electrical Supply

On the basis of configuration, transformer types are listed below.

  • 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:

5. Based on Place of Usage

On the basis of place of usage, transformer types are listed below.

  • 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:

we have given you an overview of Types of Transformer and we hope that after reading this you would gain some valuable insights and ideas out of this blog but if you are curious to know more and want to unlock all five advantages of each type with their complete limitations (free of cost/no signup required) then we think you should consider visiting Types of Transformer to get a detailed description with valuable content and information.

We are covering all topics about Transformer one by one with best of our knowledge of our “AllumiaX engineering staff” with collaboration of “General Pac engineering staff”. Till yet we have also covered Open Phase Condition in Transformers, Introduction to Current Transformers, Introduction to the Delta Wye Transformer, Fault Analysis In Power Systems and much more. Our many topics related to transformer are also almost complete and will be published soon. Stay tuned with us to learn more at Allumiax and our co-operate sponsor GeneralPac.
