Services for Transformers

Depending on the initial situation, it may be expedient from an economic standpoint to have an older or damaged transformer overhauled at one of our Siemens Energy production locations.
Based on our experience, an overhaul restores transformer availability for an extended time with no restrictions in operating reliability. There are advantages over the production of a new transformer. An overhaul and restoration are usually significantly more cost-effective and time-efficient. Our customers also experience significantly shorter outage times.

In many cases, there are no time slots for repair service or it is not  cost-effective to bring the transformer to one of our manufacturing plants for repair because of the necessary heavy transport.

In these cases we can offer our customers on-site repair. An individual solution may be elaborated depending on the existing infrastructure.

REG, the online regeneration technology, can clean aged or corrosive transformer oil, restore its dielectric properties, and increase the transformer availability. Regeneration processes requires special equipment, high competence, and long-time experience of staff. Siemens Energy operators have experience in online regeneration of more than 300 transformers with different design, connections and at various ambient temperatures.
REG, removes degradation products and corrosive compounds from transformer oil during normal transformer operations. This not only ensures operational efficiency but also offers substantial economic and ecological advantages. 

Power transformers degrade over time, with moisture in the insulating paper hastening this process. This moisture can come from insufficient drying during production, environmental damage, or the degradation process itself. A single oil treatment won't have a lasting effect as 98% of the moisture is in the insulating paper. 
Siemens Energy Transformer Service method effectively slows down the unavoidable aging process within your transformers, thus extending their lifespan. Our widely recognized DRY is a stationary and continuous transformer drying system.
