This unit involves the skills and knowledge required to solve problems in transformers. It includes safe working practices, ascertaining correct operation of transformers and solving problems as they apply to servicing, fault finding, installation and compliance work functions.The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) alternating current (a.c.) or 120 V direct current (d.c.).


For Melbourne campuses

Assessment tasks will be designed to reinforce & extend knowledge and skill competence within set & controlled parameters in accordance with each unit’s learning outcomes & performance criteria requirements, incl the setting of work based practical application tasks designed to provide evidence of competence outcomes, within periodic and scheduled timelines.
Students will be expected to demonstrate the following required skills:
*applying work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures, including:

  • identifying and assessing hazards and risks, and implementing control measures
  • applying safe working procedures when connecting and testing transformers
  • checking circuits are isolated in accordance with workplace procedures and regulatory requirements
    *solving problems with transformers, including:
  • determining the operating parameters of an existing transformer
  • altering an existing transformer circuit to comply with specified operating parameters
  • developing transformer circuits to comply with a specified function and operating parameters
  • determining the cause of low efficiency in an existing transformer
  • determining conditions causing an existing circuit to be unsafe
    *determine polarity markings for an unidentified single phase double wound transformer
    *determining the value of a transformers secondary voltage and current from nameplate data when solving problems in transformer operations
    *determining voltage and current in the windings of an auto-transformer by calculation
    *selecting transformers for specific application
    *testing serviceability of transformers
    *applying sustainable energy principles and practices
    *completing problem-solving activities documentation.

Required reading
