Job Description Job Description Job Summary This role develops expert-level capabilities in the testing of large power transformers and associated components during Final Acceptance Testing (FAT). The Test Technician plays a critical role in validating product performance, safety, and compliance with industry standards through a wide range of electrical, dielectric, and performance tests conducted in a high-voltage laboratory environment. Testing activities include control wiring verification, low- and medium-voltage electrical testing, high-voltage dielectric testing, and performance validation to ensure compliance with guaranteed electrical, thermal, and acoustic requirements. Key Responsibilities Perform comprehensive testing on large power transformers in accordance with IEEE standards and high-voltage safety requirements, including NFPA 70E compliance, Lockout/Tagout (LOTO), and fall protection when working at heights. Conduct control wiring and instrumentation verification by following schematics, test procedures, standard operating procedures, and equipment manuals. Configure, program, and troubleshoot electronic and PLC-based instrumentation. Identify and correct wiring discrepancies. Execute low- and medium-voltage electrical testing (up to 10 kV) in manufacturing and test environments, including resistance testing, capacitance, Doble, Hipot, CT testing, and dissolved gas analysis (DGA). Set up and dismantle transformers and test equipment for dielectric and performance testing. Perform transformer performance testing, including loss measurements and sound level testing at high current and voltage levels. Conduct high-voltage dielectric testing such as lightning impulse, switching surge, applied voltage, induced overvoltage, and partial discharge testing at extreme voltage levels. Document, investigate, and support resolution of nonconformities, including segregation of affected materials or components. Knowledge, Skills & Abilities Advanced understanding of electrical theory, particularly as it applies to high-voltage power systems. Strong working knowledge of high-voltage safety practices and compliance standards. Ability to read and interpret electrical schematics, wiring diagrams, and technical drawings.
