- Carrying out hands-on transformer assembly and electrical and mechanical installation work, interpreting technical drawings and specifications.
- Overseeing transformer maintenance and refurbishment activities, including component replacement, oil-related work, inspections and recommissioning.
- Conducting site audits, preparing reports and ensuring work meets quality requirements and relevant technical standards.
- Coordinating site surveys, project meetings, progress updates, documentation, equipment and logistics alongside project managers.
- Ensuring compliance with site-specific Risk Assessments and Method Statements (RAMS), health and safety procedures and safe systems of work.
- Carrying out transformer electrical testing and functional checks, identifying issues and ensuring accurate recording of results.
- Using workshop machinery, specialist testing equipment and hand tools safely and effectively.
- Maintaining professional relationships with customers, suppliers, colleagues and subcontractors.
- Travelling regularly throughout the UK and overseas to support site-based projects.
Technical Experience
You will have strong practical experience of transformer assembly, installation, testing and maintenance, with the ability to carry out and supervise a range of mechanical, electrical and diagnostic activities.
Transformer assembly and installation
- Fitting radiators, conservators, cooling systems, fans, pumps and associated accessories.
- Installing HV and LV bushings, tap changers, marshalling boxes, cable trays and trunking.
- Connecting internal leads to bushings, tap changers and current transformers (CTs).
- Sealing and gasketing flanged joints, checking mechanical fasteners to specification, and completing grounding and bonding activities.
- Installing and wiring transformer control devices, protection systems and associated equipment.
Transformer testing and functional checks
Experience with the following testing procedures and equipment will be particularly relevant:
- Insulation resistance (IR/Megger) testing.
- HV withstand testing, including overpotential testing and VLF testing for 33kV applications.
- Transformer ratio testing using a ratiometer or Testrano.
- Sweep Frequency Response Analysis (SFRA), including Omicron equipment.
- HV and LV current transformer testing using CT analysers and insulation resistance testing.
- Functional testing of Buchholz alarms and trips, pressure relief devices (PRDs), MOGs, air bag relays and oil surge relays.
- OTI and WTI temperature indicator calibration and functional checks.
- Marshalling box wiring checks and continuity testing.
- Functional checks and insulation resistance testing of fans and cooling equipment.
- Bushing tan delta testing, rupture detector relay checks and impact recorder results review.
- Transformer oil sampling and tap changer ratio testing.
- Ashridge test equipment setup.
Maintenance and refurbishment
- Draining and refilling transformer oil.
- Replacing gaskets, seals, desiccant breathers and transformer accessories.
- Inspecting and cleaning components, identifying defects and supporting remedial work.
- Replacing or upgrading monitoring equipment, indicators and protection relays.
- Supporting oil sampling for dissolved gas analysis (DGA).
- Completing torque checks, post-maintenance testing and recommissioning activities.
Health, Safety and Site Management
You'll lead by example, ensuring work is carried out safely and professionally at all times. Responsibilities include establishing safe working areas, using lifting and rigging equipment correctly, maintaining good housekeeping, identifying hazards and reporting near misses.
You'll also ensure site teams follow the correct procedures and communicate any technical, operational or safety concerns promptly.
