Transformer Assembly Oversight Technician

Full-time national traveling postion. 

Responsibilities 

• Oversee field assembly of power transformers, ensuring adherence to OEM manuals, drawings, torque charts, and work instructions. 

• Verify critical steps: tank inspection, core/coil handling, tapchanger installation and alignment, bushing assembly, gasket prep and sealing, conservator/radiators/fans/pumps installation, oil processing/vacuum dryout, and final checks. 

• Witness and document hold points, inspections, and tests per ITP/QCP (Inspection & Test Plan / Quality Control Plan). 

• Review and validate manufacturer’s specifications, drawings (GA, wiring diagrams, schematics), and field change notices before execution.

• Confirm torque values, clearances, and alignment meet specification; verify material certificates, serial numbers, and BOM traceability. 

• Ensure proper cleanliness, moisture control, and contamination prevention practices throughout assembly. 

• Witness field tests (as required): insulation resistance, turns ratio (TTR), winding resistance, power factor/DDF, excitation current, SFRA, CT polarity and ratio, and functional checks of OLTC controls/auxiliaries. 

• Confirm test instruments are within calibration and results meet acceptance criteria; escalate deviations promptly. 

Technical Qualifications 

• Transformer components (core/coil, windings, OLTC/DETC, bushings, conservator, radiators, cooling systems, gauges/relays, CTs/PTs), assembly sequencing, cleanliness and moisture control. 

• Oil handling (vacuum fill, degasification, dehydration), leak prevention, gasket selection/prep, torque practices. 

• Field test witnessing and acceptance criteria familiarity (IR, TTR, winding resistance, PF/DDF, SFRA).
