Test, fault finding and operating tools may include voltage testers, proving dead equipment, power or hand tools, control system equipment and fuse testers/multimeters. Operating environment may be during inclement or otherwise harsh weather conditions, in wet/noisy/dusty/hot areas or during night periods. Faults and abnormal operating conditions may include switch yard protection operation, switchboard protection operation, transformer protection operation, circuit/feeder protection operation; transformer faults, low oil level, loss of fans/pumps; circuit breaker faults, loss of supervisory/control supplies, low gas/oil/air pressure, failure of pump/motors and fuse failure. 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. |
