Learning Outcomes and Application | This unit of competency has been developed for Engineering Tradesperson – industrial electrician apprenticeship training and the recognition of trade-level skills in fault finding and rectifying single and three-phase transformers. It includes the operating principles of transformers, their construction and open circuit and full load characteristics; types of transformers used in transmission and distribution systems, appliances and welding machines; hazards associated with step and touch voltages, induced voltages and stored energy particularly with high voltages; earthing requirements to limit the rise of touch voltage; safe working procedures for connecting and testing and fault finding transformers.This unit covers the skills and knowledge required to meet the Electrical Regulatory Authorities Council (ERAC).Essential Performance Capabilities (EPCs):EPC 18 – Describe the basic construction, principles of operation, and typical applications of the main types of transformers.AndEssential Performance Capabilities (EPCs) classified as ‘critical’:EPC 19 – List the key safety issues of various types of transformers, including AS/NZS 3000 requirements.EPC 48 – Demonstrate knowledge and understanding of the significant dangers of High Voltage equipment and distribution systems.Some jurisdictions require the holder of this unit to be licensed or certified and users should check with the relevant authorities.Band: AUnit Weight: 4 | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. Assessors must: have vocational competency in fault finding, testing and rectifying single and three-phase transformers at least to the level being assessed with relevant industry knowledge and experience satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 and comply with the National Vocational Education and Training Regulator Act 2011 or equivalent legislation covering VET regulation in a non-referring State as the case requires. Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills. Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications. Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate. |
