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.

Useful applications

Hosting capacity in distribution grids

The increasing feed-in of fluctuating renewable energy such as photovoltaics leads to increased voltage fluctuations in low-voltage grids. In addition, there are new grid loads such as electric heat pumps or charging stations for electromobility. Conventional grid expansion has so far consisted of...

Hosting capacity in medium-voltage grids

Voltage Regulating Distribution Transformers (VRDTs) can also be used with a focus on the medium-voltage network. A selective use counteracts local voltage maintenance problems, e.g. due to large fluctuating feeders or industrial loads. In addition, there is a wider usable voltage band in the...

Optimising network topologies

An efficient distribution network has as few operating resources as possible. This saves both investments and operating costs. Voltage Regulating Distribution Transformers with ECOTAP® VPD® help to increase the efficiency of network sections. This is done, for example, by merging two local networks...

Voltage optimization

For loads such as conventional, i.e. non-frequency-controlled motors, heaters or lighting, the energy consumption is influenced, among other things, by the voltage with which the devices are supplied. If such a device is supplied with a higher voltage than necessary, it consumes more energy than...
