This unit involves the skills and knowledge required to identify, shut down and restart systems with alternate supplies.
It includes identifying the system configuration, working safely with electricity generation systems and inverters, identifying hazards and controlling the associated risks, isolation and testing for de-energisation, reinstating the system after isolation, and completing relevant documentation.
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.).
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) workplace procedures
*identifying and assessing hazards and risks, including hazards based on supply system labelling, and implementing control measures
*obtaining and checking required tools, equipment and testing devices
*reading and interpreting electrical documentation, labelling and drawings
*identifying alternative supply arrangements and configurations
*applying safe shutdown procedures
*isolating energy sources in accordance with workplace procedures and regulatory requirements, including:
*applying safe isolation practices
*identifying correct isolation device
*identifying and checking operation of control device/s
*identifying live conductors
*identifying known source of electromotive force (EMF) for testing purposes
*correctly using a voltage tester
*isolating multiple supplies, where required
*isolating under no loads
*ensuring all energy sources are isolated
*de-energising charging sources, including:
*solar charge controllers
*proving systems are isolated
*tagging-out all supplies
*ensuring all installation work complies with relevant industry standards and legislation to which the selection, installation and control equipment of each type of system must comply
*checking battery storage system integrity is in accordance with industry standards and regulatory and manufacturer requirements, including ventilation, correct isolation devices and installation position
*safely re-instating generation system to operational mode according to site documentation and manufacturer instructions
*completing required documentation and forwarding to relevant parties.
The qualified trainer and assessor will advise students of class notes, reading materials produced by VU Polytechnic and further support via VU Polytechnic e-learning system and/or in person.
