Install, construct, commission, maintain, troubleshoot, and repair equipment in high voltage switchyards, substations, communication facilities and power operations centers. This includes:--Power, distribution, grounding, phase shifting, and instrument transformers; oil, air, vacuum and gas circuit breakers; reclosers; circuit switchers; step voltage regulators; reactor and capacitor banks, motor and manually operated disconnecting switches; air compressors; uninterruptible power supply (UPS) equipment, alternate power systems, stand-by generators, transfer switches; batteries and battery chargers; motors; contactors and motor control switchgear; relays, indicating and recording instruments, condition monitoring devices, control switches, and related equipment; lighting and miscellaneous power distribution equipment; wire and cable raceway systems, and station groundings.--Substation station service systems, station grounding systems, a.c. and d.c. distribution and control system wiring, terminate, splice, direct bury high voltage cable up to 34.5 kV. Install and wire equipment on switchboards, control panels, relay panels, and in all types of electrical enclosures. Work from schematic and wiring diagrams, control board physical layouts, manufacturer's instructions, oral and written instructions. Mark up wiring diagrams and schematics when field changes are made. Safely operate vehicles up to 10,000 pounds Gross Vehicle Weight (GVWR) and vehicles of larger GVWR rating as required by specific job location. Heavy equipment associated with substation maintenance which may include utility trucks, skid steers, trenchers, tractor trailer combinations, back hoes, aerial man lifts, loaders, diggers, cranes, snow vehicles and snow plows normally used in construction and maintenance activities of transmission line, substation and communication facilities. Use various types of test equipment including power factor testing equipment (such as Doble), amp meter, voltmeters, wattmeter, multi-meter, megger, low resistance measurement devices, time travel motion analyzers, transformer turns ratio tester, transformer sweep frequency analyzer, transformer resistance tester, thermographic cameras, instrument transformer tester, battery test equipment, and insulating oil testing equipment. Perform switching in high voltage substations and switchyards. May receive clearances and hotline orders. Operate and maintain oil processing equipment such as oil filtration pumps, auxiliary oil heating units, oil degasification units, cryogenic or refrigerated moisture traps, etc. Operate and maintain Sulphur Hexaflouride (SF6) processing equipment such as carts and pumps, molecular sieves, cryogenic and non-cryogenic gas reclamation units. Operate computers and computer-based testing systems along with specialized software and firmware necessary for analyzing and maintaining sub-station equipment. Analyze, complete, and maintain both written and computer generated maintenance base line, periodic, and historical test data records for equipment tested during commissioning and maintenance of substation equipment. Recognize safety hazards and unsafe conditions, and initiate action to alleviate or eliminate hazards. Participate in job planning and jobsite tailboard discussions. Climb substation equipment and structures. What are the working conditions? Be able to wear protective apparel (such as respirators, steel-toed footwear) when required for worker safety. Work is both inside and out of doors with exposure to hazardous materials and the possibility of electric shock, falls, bruises, cuts, burns, strains, and inclement weather. May be required to fly to work sites by either fixed wing aircraft or helicopter. Work may require considerable travel requiring temporary lodging away from the duty station.
