Transformers

In 1893, ABB was one of the first companies to develop a commercial transformer, integrating it with the world’s first commercial three-phase AC power transmission link, also an ABB innovation. Today, ABB is a global leader in this vital power technology.

A transformer adjusts the electrical voltage in different parts of the grid to required levels. For example, electricity generated in a power station must be stepped up to the appropriate voltage for transmission (up to 1200 kilovolts) and then stepped down again to the distribution voltage and ultimately to (110-230 volts) which is delivered to homes.

ABB transformers are found wherever electricity is generated, transported and consumed – in power plants and substations, skyscrapers, ships and oil platforms, locomotives and railway lines, wind parks and solar power fields, heavy industries, and water and wastewater treatment plants.

ABB has continued to enhance transformer performance by developing new technologies and materials that raise efficiency, reliability, resilience and operating lifetime to new levels. ABB also developed the first digital distribution transformer – TXpert™ – to bring sensing and monitoring technology within a transformer. It integrates state-of-the-art sensors, monitoring platforms and software tools to enhance performance and reliability of the transformers.
