Keeping grids resilient at any time with Siemens Transformers
Grid resilience is a widely discussed topic today. A growing population and an increasing standard of living means that energy security has never been so important. Over the last few years major outages have taken place in different areas of the globe. Today’s challenge is not only to prevent and protect transmission grids from outage risks, but also to find effective tools to use when reacting to an emergency in order to reconnect the grid as quickly and efficiently as possible.
Maximum grid resilience is the target of all utilities and transmission operators worldwide. Siemens has developed a concept to achieve this target based on the three pillars “PREVENT”, “PROTECT”, and “REACT”. The whitepaper focuses on the challenges for the energy industry and the solutions to minimize risks and failures in transformers. Besides preventive and protective measures it also explains the Siemens-solution, which gives transformer operators the possibility to react quickly in the event that all precautions have failed.
Increased transparency and lifetime
Siemens Transformers offers a complete service portfolio including the condition monitoring assessment which combines data from several measurements to analyze the condition of a fleet of transformers. Retrofit and repair services can also help to extend the lifetime of a transformer and lower operational risks.
Highly resistant protective measures
Siemens offers tailor-made protective measures. Some of them can even be installed in transformers that are already connected to the grid. Siemens Transformers have for example developed bullet-resistant protectors. Non-magnetic steel inserts prevent overheating and ensure that the transformer is GIC-safe. Siemens also promotes the use of alternative insulation fluids like ester, which has a much higher flash and fire point, therefore reducing the risk of an explosion or fire.

Mobile Resilience Transformers
Mobile Resilience Transformers are out-of-the-box products that can also be tailor-made as customers are used to for regular power transformers. In principle, all existing innovations within the design portfolio of Siemens Transformers are available.
Compact and lightweight design
The idea was to have a power transformer that could be moved, installed, and energized within days compared to weeks within the utility’s region.
The power transformer needed to be as lightweight and compact as possible, so it can be moved to the place of emergency as fast as possible.
Easy transportation
Mobile Resilience Transformers from Siemens are easily transportable, and may not need any special transport approval, thereby providing immediate assurance.
Versatile solution
There are strategies that are based on several spare units for each voltage level, but those usually include conventional transformers with all their disadvantages: big, heavy, and very specialized for the task they were designed for.
