Special Transformers

Learning objectives

  • Describe the use of a reactor in a circuit
  • Identify the circumstances when you would use a choke in a circuit
  • Explain why an isolation transformer is used to supply power to a variable speed drive
  • Describe the windings in an auto-transformer
  • Compare the purposes of buck-boost transformers, potential transformers, and current transformers
  • Identify a scenario where a control transformer is needed
  • Identify an application that requires a K-Factor transformer

Course overview

Special transformers are used in many applications. For example, current transformers and potential transformers are important in metering and measuring electricity for control and billing.

The Special Transformer training course identifies the different special transformer types and describes how they're used. The special transformers discussed in this online course include:

  • Reactors
  • Isolation transformers
  • Auto-transformers
  • Buck-boost transformers
  • Control transformers
  • Potential transformers
  • Current transformers
  • K-factor transformers

This course is part of the Transformers training series.
