Job Description

Under general supervision, performs complex maintenance, testing, troubleshooting, repair, and installation of protective relaying and control systems associated with SMUD's generating, transmission and distribution systems.

Scope of the job:
The Electrical Technician is a specialized class involving the performance of highly technical maintenance and test work on protection and control systems associated with SMUD's generation, transmission, and distribution system.  This classification differs from that of Electrician in that the emphasis is on knowledge of what makes electrical systems work and the ability to locate malfunctions rather than the dexterity in making the mechanical repairs and/or replacements.

THIS IS A JOURNEY-LEVEL EXPERIENCED POSITION. YOU MUST HAVE COMPLETED A FORMAL 4-YEAR ELECTRICAL TECHNICIAN APPRENTICESHIP PROGRAM TO BE ELIGIBLE TO APPLY.  WHEN APPLYING FOR THIS CAREER OPPORTUNITY PLEASE INCLUDE DOCUMENTATION OF THE FORMAL 4-YEAR APPRENTICESHIP PROGRAM YOU COMPLETED.  You will have the opportunity to attach your documentation during the application process on line. If you fail to provide proof of a formal 4-year apprenticeship program you will be considered not qualified for this position. 
 

Essential Functions:

Maintenance

  • Inspect, evaluate, calibrate, test and set a wide variety of electro-mechanical and microprocessor based relays, and programmable logic controllers such as: generator protection and control, transmission or distribution line protection and control, power transformer protection and control, voltage regulators, power factor correction devices, motor and circuit breaker controls, and auxiliary systems.
  • Operate (both manual and computer controlled) relay test sets and calibration equipment manufactured by AVO, Doble, Manta and others.
  • Perform calibrations on analog and digital meters, transducers, SCADA inputs.
  • Perform off line and on line function tests and take in service readings to monitor system performance.

 
Troubleshooting and Repair

  • Check control and relay circuits, current and potential circuits, auxiliary control circuits, data and fault recorders to find, identify, and correct problems in generators, circuit breakers, power transformers, SCADA systems, and alarm systems.
  • Repair electro-mechanical relays, wiring problems and failures.
  • Make repairs to solid state and microprocessor based relay and control systems at the circuit board and component level; identify failed, faulted, and intermittent components and systems.
  • Access, retrieve, display, and evaluate digitally recorded faults, oscillographs, fault records, and displays to locate problems and check system performance.
  • Perform AC power-factor (Doble) testing, DC insulation resistance (Meggar), AC and DC high potential testing; use high current test sets, ammeters, voltmeters, watt-meters, varmeters, phase-angle meters, frequency meters, and power analyzers to find problems and failures.
  •  

Installations

  • Review design drawings such as: electrical one-lines, schematics, elementaries, logic diagrams, wiring diagrams and schedules, and relay setting and coordination orders.
  • Assist design engineers in checking circuit design integrity and effectiveness, coordinate installation plans and schedules, plan and implement acceptance tests, coordinate and perform function and start-up tests.
  • Perform detailed acceptance tests on electro-mechanical and microprocessor based relays, programmable logic controllers, CTs and PTs, meters and transducers, SCADA and alarm systems.

 
Safety

  • Use safe work practices, methods, and procedures to work on or around high-voltage (up to 230 kV) and low-voltage (600 volt or less) systems.  Work safely and effectively without direct supervision, often alone and in isolated areas.

Qualifications

EDUCATION & EXPERIENCE REQUIREMENT:

  • Completion of a 4-year Electrical Technician apprenticeship program
  • Progressively responsible experience testing, installing, and maintaining electrical protective relays used for protecting and controlling electric utility generation, transmission, and distribution systems
