Description
This unit involves the skills and knowledge required to ascertain correct operation of single and three phase alternating current (a.c.) circuits and solving circuit problems as they apply to servicing, fault finding, installation and compliance work functions.It includes safe working practices, multi-phase circuit arrangements, issues related to fault protection, power factor and multiple earthed neutral (MEN) systems and solutions to circuit problems derived from calculated and measured parameters.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) a.c. or 120 V direct current (d.c.). Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice is not held, a relevant contract of training, such as an Australian Apprenticeship, may be required. Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.
Notes
Elements and Performance Criteria
1 Identify low voltage (LV)a.c. circuit problem
- 1.1 WHS/OHS requirements and workplace procedures for work area are identified and applied
- 1.2 Hazards are identified, risks are assessed and control measures and workplace procedures are implemented
- 1.3 Safety hazards which have not previously been identified are noted on job safety assessments and existing risk control measures are implemented
- 1.4 Circuit problems are identified from documentation or work supervisor to determine the scope of work
- 1.5 Advice is sought from the work supervisor to ensure work is coordinated effectively with others
- 1.6 Sources of materials required for work are identified in accordance with workplace procedures
- 1.7 Tools, equipment and testing devices to carry out work are obtained and checked for correct operation and safety
2 Solve LV a.c. circuit problems
- 2.1 WHS/OHS risk control measures and workplace procedures for carrying out work are followed
- 2.2 Need to test or measure live work is determined in accordance with WHS/OHS requirements and, as required, conducted in accordance with workplace safety procedures
- 2.3 Circuits/machines/plant are checked and isolated, as required, in accordance with WHS/OHS requirements and workplace procedures
- 2.4 Methodical techniques are used to resolve circuit problems from measured and calculated values as they apply to single and three phase LV circuits in accordance with workplace procedures
- 2.5 Existing circuits are altered to comply with power factor correction in compliance with industry standards
- 2.6 Power factor of a circuit is calculated from given measurements
- 2.7 Low power factor is improved by altering the reactive power of a circuit
- 2.8 Unplanned situations are responded to in accordance with workplace procedures in a manner that minimises risk to personnel and equipment
- 2.9 Problems are resolved without damage to apparatus, circuits, the surrounding environment or services using sustainable energy practices
3 Complete work and document activities
- 3.1 WHS/OHS work completion risk control measures and workplace procedures are followed
- 3.2 Worksite is cleaned and made safe in accordance with workplace procedures
- 3.3 Justification for solutions used to resolve circuit problems is documented in accordance with workplace procedures
- 3.4 Work completion is documented and an appropriate person/s notified in accordance with workplace procedures
