ECOTAP VPD

THE COMPACT CLASS FOR DISTRIBUTION TRANSFORMERS.
Superior technology. Compelling economics.


Product description

In distribution grids, non-voltage regulation transformers, which cannot respond to changes in voltage under load, are generally used. ECOTAP VPD turns these fixed distribution grid transformers into regulating transformers which keep voltage stable in public, industrial, and private distribution grids. They compensate for fluctuations in the medium voltage and respond dynamically to changes in feed-in and load at the low-voltage level.

This opens up new opportunities, not just for utilities but also for industrial companies or operators of wind turbines, all of whom stand to gain from distribution grid transformers regulated with ECOTAP VPD.
