Ecotap VPD On-load Tap-changer

Compact, reliable, and maintenance free: With the superior vacuum technology for on-load tap-changers from Maschinenfabrik Reinhausen (MR), distribution transformers can now be regulated. They maintain a constant voltage in public, industrial, and private distribution grids by compensating for fluctuations in the medium and, if necessary, high-voltage levels and responding dynamically to changes in the feed-in and demand at the low-voltage level.


The control and regulating unit 1 continuously measures the secondary voltage 2 and automatically outputs a signal to the tap changer when it needs to change the transformer ratio 3. The control and regulating unit can also be connected with SCADA systems 4 to support more sophisticated voltage control schemes.
