ECOTAP® VPD® III
The compact class for distribution transformers
ECOTAP® VPD® is the solution for all operators who have to maintain voltage in a defined and stable band in public, industrial and private distribution grids. Compact and able to be standardized, with a large control bandwidth even in fine steps, for autonomous, automatic voltage regulation and a communication interface: ECOTAP® VPD® is a highly economical solution while maintenance-free over the service life of the transformer. More and more operators are therefore introducing the voltage regulating distribution transformer in to their strategic network planning. It is also perfectly suited for grid-code-compliant connection of wind or solar parks.
