Test Technician - 3rd Shift

Power Transformer Testing Technician

This position develops expert level skills to perform testing of large power transformers and their components during Final Acceptance Test (FAT).

Transformer testing comprises several key procedures, including control wiring checks for the verification of fans, LTC, and electronic monitor operations, and Low/medium-voltage tests like ratio, capacitance, Hipot, and frequency response. FAT includes high voltage testing to verify guaranteed performance (Losses) and thermal characteristics in addition to dielectric testing like lightning & switching impulse, Induce Over voltage Test, and partial discharge measurements.

Primary duties will be to perform various tests listed below on large Power Transformers complying with IEEE standards and HV Safety protocols per NFPA70E including Lockout-Tagout (LOTO) and Fall protection while working at heights.

• Control Wiring and Instrumentation: Perform comprehensive pre-test verification and testing of control wiring and instrumentation, following schematics, test procedures (TPs), test standard operating procedures (TSOPs), and device manuals. Set and program electronic and PLC-based instrumentation, troubleshoot, and correct wiring errors.
• Low/Medium Voltage Testing: Perform preliminary and low-voltage electrical tests (up to 10KV) in both manufacturing and test floor environments. This suite of tests encompasses Doble, Hipot, resistance, DGA, CT Test
• Test Setup/Support: Setup and teardown of test equipment and transformers for/after Dielectric and performance tests
• Performance Testing: Conduct performance test like Transformer losses and Sound level measurement, which can be up to 345KV and 20,000A.
• High-Voltage/DiElectric Testing: Conduct high-voltage tests such as Lightning Impulse, Switching Surge, and Applied voltage and induced over voltage test, that can be as high as 2000KV.
