This unit involves the skills and knowledge required to install, configure and commission low voltage (LV) micro-hydro systems rated up to 6.4 kilowatt (kW).

It includes preparing to install LV micro-hydro systems, installing LV micro-hydro systems, and completing and reporting installation activities.

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).

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, is 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.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

micro-hydro systems LV installation and maintenance processes, including:

micro-hydro systems LV installation processes encompassing:

selection of an appropriate micro-hydro system taking into account the topology of the site, local council approvals, environmental considerations, site access and transport of equipment, water and power transmission distances and daily and seasonal load profiles

appropriate methods, using appropriate safety procedures, for dam or weir construction, watercourse construction and/or penstock installation, and turbine installation

appropriate installation, testing, commissioning, fault diagnosis and rectification procedures using appropriate safety procedures

schematic and wiring diagrams for the micro-hydro system showing the general circuit layout and protection between the micro-hydro system, batteries, inverter and loads according to AS/NZS 3000 Electrical installations (known as the Australian/New Zealand Wiring Rules), AS/NZS 4509 Stand-alone power systems, and AS 4086.2 Secondary batteries for use with stand-alone power systems – Installation and maintenance requirements
