Description
This unit covers undertaking accuracy checks on instrument transformers and includes proving their functionality. It also includes both current and voltage instrument transformers having various operating principles, which are designed for metering, protection, monitoring or control usage. It also encompasses tasks associated with the isolation from other secondary circuits, inspection, measurement of excitation curves, measurement of phase and ratio errors and comparison of results with previous historical results and/or published specifications.The application of the skills and knowledge described in this unit may require a licence/registration to practice in the workplace subject to regulations for undertaking of electrical work. Other conditions may apply under state and territory legislative and regulatory licencing requirements which must be confirmed prior to commencing this unit.
Notes
Elements and Performance Criteria
1 Plan for accuracy checks on instrument transformers
  • 1.1 Work health and safety (WHS)/occupational health and safety (OHS) practices/procedures and environmental and sustainable energy procedures, which may influence the performance of accuracy checks on instrument transformers, are reviewed and determined
  • 1.2 Purpose of the performance of accuracy checks on instrument transformers is established after data is analysed and expected outcomes of the work are confirmed with appropriate personnel
  • 1.3 Organisational established procedures on policies and specifications for the performance of accuracy checks on instrument transformers are obtained or established with appropriate personnel
  • 1.4 Testing procedures are discussed with/directed to appropriate personnel in order to ascertain the project brief
  • 1.5 Testing parameters are established from organisational established procedures and policies and specifications
  • 1.6 Equipment/tools and personal protective equipment (PPE) are selected based on specified performance criteria and established procedures
  • 1.7 Work roles and tasks are allocated according to requirements and individual competencies
  • 1.8 Work is prioritised and sequenced for the most efficient/effective outcome, completed within an acceptable timeframe, to a quality standard and in accordance with established procedures
  • 1.9 Liaison and communication issues with others/authorised personnel, authorities, clients and land owners are resolved and activities coordinated to carry out work
  • 1.10 Risk control measures are identified, prioritised and evaluated against the work schedule
  • 1.11 Relevant work permits are secured to coordinate the performance of work according to requirements and/or established procedures
2 Carry out accuracy checks on instrument transformers
  • 2.1 Circuit/systems modelling is used to evaluate alternative proposals in accordance with established procedures
  • 2.2 WHS/OHS and sustainable energy principles, functionality and practices to reduce the incidents of accidents and minimise waste are incorporated into the project in accordance with requirements and/or established procedures
  • 2.3 Performance of accuracy checks on instrument transformer decisions are made on the basis of safety and effective outcomes according to requirements and/or established procedures
  • 2.4 Mathematical and/or engineering models of the performance of accuracy checks on instrument transformers are used to analyse the effectiveness of the finished project in accordance with requirements and established procedures
  • 2.5 Technical advice is given regarding potential hazards, safety risks and control measures so that monitoring and preventative action can be undertaken and/or appropriate authorities consulted, where necessary, in accordance with requirements and established procedures
  • 2.6 Essential knowledge and associated skills are applied to analyse specific data and compare it with compliance specifications to ensure completion of the project within an agreed timeframe according to requirements
  • 2.7 Accuracy checks on instrument transformers are undertaken according to requirements and established procedures
  • 2.8 Work teams/groups are arranged/coordinated/evaluated to ensure planned goals are met according to established procedures
  • 2.9 Solutions to non-routine problems are identified and actioned, using acquired essential knowledge and associated skills, according to requirements
  • 2.10 Quality of work is monitored against personal performance agreement and/or established organisational and professional standards
  • 2.11 Strategic plans are developed incorporating organisation initiatives in accordance with established procedures
3 Complete the performance of accuracy checks on instrument transformers
  • 3.1 Final review of test results on instrument transformers is undertaken to ensure they comply with all requirements and includes all specifications and documentations needed to complete the project
  • 3.2 Appropriate personnel are notified of completion and reports and/or completion documents are finalised/commissioned
  • 3.3 Reports and/or completion documents are submitted to relevant personnel/organisations for approval and, where applicable, statutory or regulatory approval
  • 3.4 Approved copies of the performance of accuracy checks on instrument transformers documents are issued and records are updated in accordance with established procedures
