High Voltage Test Technician

Test Technician – High Voltage / Transformer Testing About the Role

We’re seeking a Test Technician to support electrical testing and Factory Acceptance Testing (FAT) for large power transformers. This role involves hands-on electrical testing, control wiring verification, and assisting with high‑voltage and dielectric test operations. If you have a strong electrical foundation and want to build advanced skills in high‑voltage equipment testing, this is an excellent fit.

• Perform control wiring checks and verify operation of fans, LTCs, sensors, and monitoring systems
• Read and interpret electrical schematics, wiring diagrams, and test procedures
• Conduct low/medium‑voltage electrical tests (ratio, resistance, capacitance, Hipot, Doble, CT testing)
• Assist with setup and teardown of transformers and test equipment
• Support high‑voltage tests (Lightning Impulse, Switching Impulse, Applied Voltage, Induced Over‑Voltage, Partial Discharge)
• Document test data, investigate nonconforming results, and ensure proper handling of defective components
• Follow all high‑voltage safety protocols including NFPA
  70E, Lockout-Tagout (LOTO), and fall‑protection procedures

• Strong understanding of electrical theory and three‑phase power
• Ability to read and interpret electrical schematics and wiring diagrams
• Experience using electrical test instruments (multimeters, oscilloscopes, HV test equipment)
• Hands‑on troubleshooting skills
• High attention to detail and accurate documentation habits
• Comfort working in a manufacturing/test‑floor environment with strict safety requirements

• Transformer, switch gear, substation, or utility equipment background
• Experience with PLCs or instrumentation
• Field commissioning or FAT experience

You qualify with ANY of the following:

• Associate degree in Electrical/Power/High Voltage/Utilities Engineering or related field
• OR 2+ years of transformer FAT testing or field commissioning
• OR Journeyman/Master Electrician with relevant high‑voltage or utility experience
• OR 2–4 year degree (any discipline) + 2+ years technical experience in testing, field service, or electrical manufacturing

• Opportunity to grow into advanced high‑voltage testing
• Hands‑on work with large electrical power equipment
• Strong technical development and career progression
