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. Inspection should be planned with the appropriate parties to determine access, conditions and work requirements. WTG systems may include blade pitch systems, weather monitoring systems, converters, generator slip systems, compensation systems, safety chain systems, generators, gearboxes, and yaw control systems. WTG communication systems may include: TCP/IP network, Ethernet, fibre optic, wireless, Fieldbus (IEC 61158), FASTBUS (IEEE 960-1986), CANCOMM, HART communication protocol, PROFIBUS, internet and hard wired. WTG control systems may include one or a combination of: electronic systems, distributive control systems, SCADA, electrical systems, pneumatic systems, hydraulic systems, mechanical systems and PLC systems. Equipment and components may include: circuit boards, circuit breakers, transformers, rectifiers, , inverters, pressure sensors, power factor correction circuitry, resistors, electric motors, control cabinets, protection equipment, transmitters, switches, temperature sensors, indicators, meters, proximity switches, encoders, resolvers, thyristors, fire detectors, smoke detectors and vibration sensors, fibre optic cables, Category 5 and 6 communication cables, wireless transmitters and receivers fuses, circuit breakers, timers, contactors, contacts, coils, relays, inductors, capacitors, bridge rectifiers, diodes, heat sinks, solenoids, overloads, plug in printed circuit boards, switches, plugs, cables and thermistors. Fixed wiring tests can refer to: voltage, resistance, current, polarity, loop impedance, insulation resistance and continuity tests. Materials may refer to: insulation tapes, heat shrink, sleeving, spiral binding, cable ties, solder, lubricants, oil, greases, and sealants, cleaning chemicals, lugs, connectors, terminal blocks, cable markers and identification labels. Tools, equipment and test and measurement instruments may include: multimeter, frequency counter, frequency generator, hand tools, power tools, lifting equipment, laser alignment tools and specialised test equipment. Fault indicators may include: self test systems, software logs, indication lamps, alarms and flag relays. Setup and calibrate may include loading software, setting parameters, energising components, checking tension, checking alignments, calibrating brakes, setting north points, terminating cables, cleaning, removal of packaging, filling automatic lubrication systems Work may be performed in service or out of service. Work completion details may include: plant and maintenance records, warranty documents job cards, check sheets, punch lists and on device labelling updates. Work site environment may be affected by weather or nearby animals, plant or processes, eg heat, noise, dust, oil, cattle, farm animals, native animals, snakes, water, height and chemicals. Isolations can refer to electrical, mechanical or other associated processes. Large Scale Wind Generators (WTGs) include systems having a rating of greater than 10 kW Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1 Preliminary Information and Glossaries. |
