About The Position

The Power Transformer Testing Specialist is responsible for performing advanced diagnostic testing, commissioning, troubleshooting, and condition assessment of Medium, Large, EHV (Extra High Voltage), and UHV (Ultra High Voltage) power transformers. This role requires expert-level knowledge of IEEE transformer testing standards, electrical testing methodologies, and industry test equipment. The specialist ensures the reliable operation of critical power assets by conducting high-accuracy test procedures, compiling complex data, and providing technical reports, working collaboratively with engineering.

Requirements

Associate or bachelor’s degree in electrical engineering, Power Engineering, or related field (or equivalent experience).
5+ years of experience performing transformer testing in utility, industrial, EPC, or field-service environments.
Expert knowledge of IEEE C57 transformer testing standards and field-testing practices.
Proficiency with transformer testing instruments (Doble, Omicron, Megger, etc.).
Strong understanding of transformer construction, theory, insulation systems, and failure modes.
Ability to read and interpret technical drawings, schematics, and OEM manuals.
Excellent analytical, troubleshooting, and problem-solving skills.
Strong written and verbal communication abilities.
Ability to travel to job sites, sometimes on short notice.

Nice To Haves

NETA Level III or IV certification (or equivalent experience).
Experience with EHV/UHV transformer commissioning (230kV–765kV and above).
Training of certification in SFRA, PD testing, or advanced diagnostic methods.
Experience working with EPCs, IOUs, IPPs, or large industrial clients.
Familiarity with digital transformer monitoring systems.
Experience with High Voltage breakers a plus

Responsibilities

Perform advanced field testing on Medium, Large, EHV, and UHV transformers in accordance with IEEE standards (including IEEE C57 series).
Ability to execute the full suite of transformer diagnostic testing, such as: Insulation Power Factor (Doble PF/Tan Delta), Excitation current testing, Winding resistance testing, TTR (Turns Ratio Testing), Sweep Frequency Response Analysis (SFRA), Dielectric Frequency Response (DFR), Leakage Reactance / Short-circuit impedance, Capacitance and insulation resistance measurements, Partial discharge testing (when required), Oil sampling, dissolved gas analysis (DGA), and moisture assessment
Operate and maintain advanced test equipment from OEMs such as Doble, Omicron, Megger, Vanguard, and others.
Lead and support transformer energization, acceptance testing, and commissioning activities for new or refurbished power transformers.
Verify compliance with utility, EPC, and OEM specifications.
Perform on-site troubleshooting for abnormal transformer conditions and support root-cause investigations.
Collaborate with engineering to analyze test results and trends to evaluate transformer health and recommend corrective actions.
Compile and support the preparation of detailed technical data with interpretations, conclusions, and maintenance recommendations.
Communicate test results and findings to engineering teams, utility clients, and project managers.
Follow as OSHA, NFPA 70E, and company safety procedures during testing and field service work.
Ensure testing is performed in alignment with IEEE, ASTM, NETA, and OEM guidelines.
Support the maintenance, calibration, and proper care of all test instruments and PPE.
Serve as the field process expert on transformer testing, working with Engineering.
Mentor junior technicians and assist with training on field testing methods.
Participate in continuous improvement of testing procedures, workflows, and documentation.
