Distribution Transformers provide the necessary power for systems and buildings on the last transformation step from the power station to the consumer. Accordingly, their operation must be reliable, efficient and at the same time silent.

FITformer® REG - Regulated Distribution Transformer
Regulated Distribution Transformer
Our power supply system is gradually changing: Renewable energy brings about higher complexity in the system. Decreases in load, their power feed-in and the storage capability sometimes fluctuate considerably.
The solution is to modify the network infrastructure: the system of the future must be efficient, effective and therefore flexible.
The Siemens Regulated Distribution Transformer FITformer® REG can change its voltage ratio under load. This helps the power supplier to remain within the admissible voltage range. For this purpose the transformer disposes of a three-step low voltage load regulator.

The voltage in the network can vary substantially, due to changes in the operating conditions. For instance the voltage in high load conditions with no decentralized feed-in is very different from that in low load conditions with maximally decentralized feed-in. While with a higher feed-in the voltages are notably higher, they are reduced in high load conditions.
The challenge for network operators lies in the maximum voltage difference between high load conditions and low load conditions in a node, for example in Photovoltaics
(∆u ; s. Graphic 1).
Medium-voltage and low-voltage systems change due to the increasing integration of decentralized renewable power supplies and the emerging electromobility trend in the public transport sector.
While the increasing need for load capacity can be provided by means of system expansion, the effects due to alternating direction of power flow, load fluctuations and voltage range limitation can only be handled with intelligent solutions.
Intelligent transformer substations from Siemens offer the optimum solution concept:
