Inspection should be planned with the appropriate parties to determine access, conditions and work requirements. Equipment may include HV transformers, tap changers, switchgear and associated control panels, alarms, alternators, igniters, flame scanners, unit control panels, mimic panels, conveyors, alternator cooling systems, automatic voltage regulators, sootblowers, vibratory feeders, battery chargers, precipitators and overhead cranes. Materials may include masonry anchors, bolts, nuts, washers, screws, rivets, saddles, clips, brackets, solvents, adhesives, insulation tapes, heat shrink, sleeving, spiral binding, cable ties, solder, lubricants, oil, greases, sealants, lugs, connectors, terminal blocks, cable markers, identification labels, transformer oil, jointing compound, cable compounds and phase markers. Components may include fuses/circuit breakers, timers, contactors, contacts, coils, relays, solenoids, overloads, switches, plugs, busbar, cable, fans, thermostats, elements, seals and motor bearings and brush gear. Test and measurement instruments may include multimeters, tong testers, insulation resistance/continuity tester, ductor tester, growlers, overload injection tester, liquid leak tester, pressure gauges, vacuum gauges, dew point test equipment, insulating oil tester and specialist test equipment. Fault finding and diagnostic techniques may include linear approach, half split rule, sensory detection, loop test, insulation/resistance and continuity tests. Fault indicators may include indication lamps, LEDs, alarms and flag relays. Work may be performed with equipment on line. Work completion details may include, plant and maintenance records, job cards, check sheets and on device labelling updates. Work site environment may be affected by nearby plant or process, e.g. heat, noise, dust, oil, water and chemical. Isolations can refer to electrical/mechanical or other associated processes. 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 Volume 2, Part 1. |
