Future-proof energy supply

with transformer solutions from the R&S Group

Climate targets, decentralised grid feed-in, and security of supply present new challenges for grid operators. The R&S Group supplies transformers for power generation, transmission, and distribution – efficient, reliable, and globally available.

Energy supply in transition

Access to energy is a fundamental prerequisite for social progress. But sustainable electricity distribution is no longer a given:

Decarbonization, rising electricity demand, decentralised grid feed-in from wind and solar, digitalisation, and political targets are changing the rules of the game – worldwide.

As an experienced partner to the energy supply industry with over 100,000 transformers installed worldwide, the R&S Group supports grid operators, municipal utilities, and energy companies in implementing a stable and cost-efficient power supply – today and tomorrow.

Why R&S for power generation, transmission and distribution?

High grid stability despite volatile feed-in
Minimise losses and reduce CO₂ emissions – with transformers optimised for efficiency: amorphous cores, optimised core laminations, and smart control.

High grid stability despite volatile feed-in
Our transformers ensure voltage and frequency – even in the event of highly fluctuating power generation from wind and solar plants.

Future-oriented engineering
All solutions are ready for digitalisation, load flow control, cybersecurity and smart grid requirements.

Total Cost of Ownership in View
Durable designs, minimal maintenance requirements and low operating losses ensure low life cycle costs.

Global brands, local expertise
Production in Europe and the Middle East by Rauscher & Stoecklin, ZREW, Tesar and Kyte Powertech – for short distances and high availability.

Grid operators are seeking solutions to further reduce energy losses without compromising the security of supply. Our low-loss transformers make an essential contribution to achieving national and European climate targets.

Digitization
The digitalisation of power grids is transforming the entire energy sector. Our transformers are ready for smart grid applications, IoT sensors, and enable precise control and remote monitoring – while simultaneously focusing on cybersecurity.
Energy storage & volatile feed-in
Weather-dependent generation (wind, PV) presents challenges with frequency control and grid regulation. Our transformer solutions support load flow control, peak load management, and the integration of storage solutions.
