This role focuses on the testing, maintenance, and diagnostics of high-, medium-, and low-voltage apparatus, ensuring safe, reliable, and compliant operation of critical power infrastructure. The technician works in both greenfield and brownfield substations at various stages of energization and contributes directly to safe energization, troubleshooting, and ongoing system performance.
Responsibilities
Perform field testing, maintenance, and commissioning of electrical apparatus including low-, medium-, and high-voltage circuit breakers, pad-mounted and power transformers, current transformers (CTs), potential transformers (PTs), substation equipment, and power cables.
Conduct testing and verification of low-, medium-, and high-voltage power cables, including insulation and integrity assessments, to ensure system reliability and safety.
Test and evaluate ground grid systems and perform related measurements to confirm proper grounding and compliance with safety standards.
Perform oil sampling and diagnostics on transformers and related equipment, interpret results, and support recommendations for maintenance or corrective action.
Work in greenfield and brownfield substations at various stages of energization, supporting commissioning, energization, and ongoing maintenance activities.
Understand, interpret, and work within three-phase electrical systems, including reading and applying three-line diagrams and related documentation.
Follow and execute lockout/tagout (LOTO) procedures and other safety protocols to ensure safe work practices in energized and partially energized environments.
Support power systems commissioning activities, including functional testing, verification, and troubleshooting of electrical systems and equipment.
Troubleshoot electrical systems and equipment issues in the field, identify root causes, and implement or recommend corrective actions.
Collaborate with field teams, engineers, and project personnel to plan, sequence, and execute testing and commissioning activities efficiently and safely.
Document test results, findings, and maintenance activities accurately and clearly for reporting and record-keeping purposes.
Travel to job sites across Colorado, and occasionally out of state, to support field testing, commissioning, and maintenance assignments.
