The trend towards digitalization in after-sales support is transforming the industry. Remote monitoring and diagnostics capabilities have become particularly valuable, especially in the wake of global events that have limited travel. I've been involved in several projects where transformers were commissioned and troubleshot entirely through remote systems.

Another emerging trend is the shift towards performance-based service contracts. Some manufacturers are now offering guarantees on transformer uptime and efficiency, with financial penalties if they fail to meet agreed-upon performance metrics. This approach aligns the interests of the manufacturer and the client, ensuring ongoing commitment to performance.

The quality of a manufacturer's digital infrastructure for support is becoming increasingly important. User-friendly portals for accessing documentation, ordering parts, and scheduling maintenance can significantly improve the customer experience. I recently worked with a client who chose a slightly more expensive supplier primarily because of their superior digital support tools.

As we look to the future, I expect to see even more integration of AI and machine learning in customer support. Predictive analytics will likely become more sophisticated, potentially predicting issues months or even years in advance. We might also see the emergence of self-diagnosing and self-healing transformer technologies, further reducing the need for human intervention.

In conclusion, while the quality of the transformer itself is crucial, the level of after-sales support can make or break the long-term success of a power infrastructure project. As you evaluate manufacturers, be sure to give significant weight to their customer service and support capabilities.

Conclusion

The power transformer market in 2025 is led by manufacturers who excel in innovation, global presence, sustainability, and customer support. ABB, Siemens, GE, TBEA, and Hitachi Energy are at the forefront, shaping the industry's future with their technological advancements and strategic approaches.
