Distribution transformers with on-load tap changer

Distribution transformers with on-load tap-changers ensure that the voltage in public and industrial distribution grids remains stable by balancing fluctuations in the medium voltage and dynamically reacting to supply and load changes in the low voltage.

This means that additional renewable energies can be incorporated into the distribution grid without having to perform expensive grid expansion work. They make it easier to connect wind farms and solar parks without incurring excessive costs, stabilize industrial processes, and even help to keep energy costs in industrial environments low. What’s more, thanks to actively selected voltage levels, they even make it possible for electrical distribution grids to operate in a way that keeps losses as low as possible.
