You will join the team working on oil-filled and cast-resin transformers for power converter applications. You will contribute to an ongoing renovation program aimed at progressively replacing oil-filled transformers with modern cast-resin transformers, driven by environmental considerations.
The role is hands-on and site-based, involving close interaction with equipment in operation. You will collaborate closely with a team of engineers, technicians, and external contractors for the integration of transformers within complex power converter systems. The role also offers you exposure to advanced low-voltage and medium-voltage power systems, and it provides you with many opportunities to further develop your practical and diagnostic skills in a high-level technical environment.
Your responsibilities
-
Support installation and commissioning activities for new or refurbished transformers, including verification of protection, control, and interlock circuits.
-
Contribute to the integration of transformers into upgraded power converter systems, ensuring correct connection and compatibility with control and protection equipment.
-
Prepare basic 3D mechanical drawings or layouts for simple integration tasks when required.
-
Contribute to technical documentation: electrical diagrams, test reports, installation procedures, and equipment inventory updates.
-
Perform routine inspections, diagnostics and functional tests of oil-filled and cast-resin transformers.
-
Carry out preventive and corrective maintenance activities on transformers.
Your profile
-
Initial experience working in electrical installations (low and/or high voltage).
-
Initial experience in operation and maintenance of electrical systems and equipment.
-
Practical experience with troubleshooting and diagnostics of electrical installations is considered an asset.
-
Experience in the field of power transformers is an advantage.
Skills
-
Electrical safety awareness.
-
Ability to read and understand electrical schematics and simple mechanical drawings.
-
Familiarity with electrical measurements (multimeter, insulation tester, oscilloscope).
-
Ability to work hands-on on site, in collaboration with technicians, engineers and contractors.
-
Basic knowledge of 3D CAD tools is an asset.
-
Spoken and written English, with a commitment to learn French.
