Every transformer tells a story. 

Some have operated reliably for more than 40 years, supporting growing cities, industrial facilities and critical infrastructure through changing patterns of electricity demand. Others have adapted to the rapid growth of renewable energy, data centres and electrified transport, often operating under conditions they were never originally designed to accommodate. 

When these assets require refurbishment or remanufacturing, sophisticated equipment and advanced diagnostics are only part of the solution. 

The other essential ingredient is people. 

Across Europe, highly skilled engineers, technicians and repair specialists continue to play a vital role in extending transformer life, improving reliability and helping utilities maximise the value of existing infrastructure. Their expertise often determines whether an ageing transformer can continue operating safely for another decade or whether replacement becomes the better option. 

As demand for transformers continues to grow, these specialist skills are becoming one of the industry's most valuable resources. 

Experience cannot be manufactured overnight 

Transformer remanufacturing combines mechanical engineering, electrical engineering, materials science and decades of practical experience. 

Every refurbishment project begins with technical assessment. 

Engineers evaluate the condition of insulation systems, windings, cores, tap changers, bushings and cooling equipment before determining the most appropriate course of action. 

Although digital diagnostics provide valuable information, interpreting that data requires experience. 

Understanding whether abnormal dissolved gas analysis results indicate normal ageing or the early stages of failure often depends on years of working with similar assets. The same applies to insulation testing, thermal assessments and visual inspections. 

Much of this expertise has been developed over decades. 

Passing it to the next generation is becoming increasingly important. 

A growing skills challenge 

The electrical manufacturing industry is expanding rapidly. 

Utilities are investing in grid reinforcement, renewable integration and network modernisation. Manufacturers are increasing production capacity to meet unprecedented demand for transformers and associated equipment. 

At the same time, many experienced engineers are approaching retirement. 

This creates two challenges simultaneously. 

The industry needs more skilled people than ever before, while also preserving the specialist knowledge held by experienced professionals. 

Replacing technical expertise is not simply a recruitment challenge. 

It requires structured knowledge transfer, mentoring and long-term investment in engineering development. 

Without this, valuable practical experience risks being lost just as demand for transformer expertise reaches record levels. 

Technology is supporting engineers, not replacing them 

Digital technologies have transformed many aspects of transformer maintenance and remanufacturing. 

Condition monitoring systems, predictive analytics, digital inspection tools and asset management platforms all provide engineers with better information than ever before. 

However, these technologies work best when combined with human expertise. 

Data identifies trends. 

Engineers determine their significance. 

Artificial intelligence may highlight unusual operating behaviour, but experienced specialists understand how those findings relate to transformer design, operating history and environmental conditions. 

Rather than replacing skilled engineers, digital technologies allow them to make faster, more informed decisions. 

The future of remanufacturing depends on combining engineering judgement with increasingly sophisticated diagnostic capabilities. 

Building careers across the transformer value chain 

The workforce supporting transformer remanufacturing extends far beyond repair workshops. 

It includes: 

• Electrical design engineers 

• Manufacturing engineers 

• Materials specialists 

• Test and commissioning engineers 

• Condition monitoring experts 

• Asset managers 

• Service engineers 

• Quality assurance specialists 

• Automation engineers 

• Digital technology providers 

This diversity reflects the increasingly connected nature of modern electrical manufacturing. 

As transformers become more intelligent and manufacturing becomes more digital, career opportunities continue to expand. 

The challenge is ensuring enough new talent enters the sector while existing expertise is shared effectively. 

Remanufacturing depends on collaboration 

Successful refurbishment projects rarely involve one organisation alone. 

Utilities contribute operational history and maintenance records. 

Manufacturers provide design knowledge and engineering support. 

Testing specialists deliver detailed condition assessments. 

Repair organisations carry out specialist refurbishment work. 

Component suppliers provide replacement parts and upgraded technologies. 

Each organisation contributes different expertise. 

Strong collaboration ensures every decision is based on the best available technical information while maintaining the reliability expected from critical infrastructure. 

This collaborative approach is becoming increasingly important as projects become more technically demanding. 

Investing in the next generation 

Developing specialist engineering capability requires long-term commitment. 

Many organisations are expanding apprenticeship programmes, graduate recruitment initiatives and internal training schemes to prepare future engineers for increasingly complex electrical infrastructure. 

Mentoring plays an especially important role. 

Experienced engineers possess practical knowledge that is difficult to capture in technical manuals or operating procedures. 

Working alongside these specialists allows younger engineers to develop both technical understanding and professional judgement. 

The industry also benefits from stronger collaboration with universities, research organisations and professional engineering bodies. 

Encouraging more students to pursue careers in electrical engineering will be essential if the sector is to meet future demand. 

Knowledge sharing strengthens the entire industry 

One of the industry's greatest strengths is its willingness to share experience. 

Technical conferences, industry forums and professional networks allow engineers to discuss common challenges, compare solutions and learn from one another's experience. 

This exchange of knowledge supports continuous improvement across manufacturing, maintenance and asset management. 

As transformer technology continues to evolve, opportunities to learn from different sectors of the electrical manufacturing industry become increasingly valuable. 

Insights from digitalisation, automation, advanced materials and manufacturing technologies often benefit organisations throughout the wider value chain. 

Knowledge sharing therefore supports innovation just as effectively as investment in new equipment. 

People remain the industry's greatest asset 

The future of transformer remanufacturing will depend on more than manufacturing capacity, material availability or digital technology. 

It will depend on people. 

Engineers capable of diagnosing complex faults. 

Technicians restoring critical assets. 

Manufacturing specialists improving production processes. 

Asset managers balancing reliability, cost and long-term investment. 

Together, these professionals ensure existing transformer fleets continue supporting Europe's electricity networks while new infrastructure is built. 

As electrification accelerates, their contribution will only become more important. 

Connecting expertise across the value chain 

CWIEME Berlin brings together the people shaping the future of electrical manufacturing. 

From transformer manufacturers and utilities to machinery providers, testing specialists, materials suppliers and digital technology companies, the event creates opportunities to exchange knowledge, strengthen partnerships and explore practical solutions to the industry's shared challenges. 

It is these conversations that help transfer knowledge between generations, encourage collaboration across sectors and support the continued development of specialist engineering expertise. 

Transformer remanufacturing may depend on advanced diagnostics, innovative materials and sophisticated manufacturing processes. 

But behind every successful refurbishment project is a team of skilled professionals whose knowledge keeps Europe's electricity networks operating safely and reliably. 

As the industry prepares for the next decade of growth, investing in those people may prove to be one of the most important decisions of all.
