10) This relates to the competency standard unit as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance. Maintenance tasks on wind turbine generators may include: Climbing equipment, including personnel lifts, climb assist, elevators Winches and Cranes Ladders Hydraulic equipment, gearboxes, yaw and pitch gear, turbine braking equipment. Maintenance may include: visual inspections, replacement of mechanical components, checking the tension of bolts, replacing bearings, replacing seals and o-rings, condition monitoring, lubrication, testing of equipment for correct operation, and lubrication of equipment. Oil sampling techniques Testing includes visual, auditory and olefactory sensing Checking of sensors through SCADA Tools may include spanners, screwdrivers, side cutters, pliers, high torquing wrench, grease pump, endoscopic inspection tools Test equipment may include laser alignment tools, laptop computers, PC tablet, smart phones and other data acquisition tools and equipment. Consumables may include gearbox oils, hydraulic oil, bearing grease, paint, detergents, Loctite Cleaning, including the following equipment and gear: Grease from bearings Oil spills Dust Water Salt Hydraulic schematic diagrams Wind turbine generator range is from 50kW and greater Work completion details may include plant and maintenance records, job cards, check sheets, on device labelling updates and reporting and/or documenting equipment defects. Work site environment may be affected by nearby plant or processes and climatic conditions e.g. wind speed, chemical, heat, dust, noise, height and oil, acid and alkalie spills and vapours. Location of wind turbine generators may be in urban, suburban, regional or rural locales and environments. Isolations can refer to electrical/mechanical or other associated processes. Generic terms used throughout this Vocational Standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms that apply are given in the Glossaries, Section 2.1 of this Training Package. |
