About us

Our company is active in power engineering and consists of Maschinenfabrik Reinhausen GmbH (MR) and 36 subsidiaries and 6 affiliated companies globally. In the past financial year, 3,300 employees produced a turnover of 750 million euros.
Our core business is the regulation of power transformers. This is done above all with the aid of tap changers, which adapt the transmission ratio of the primary to secondary winding to changing load ratios and, together with additional, innovative products and services, ensure an interruption-free power supply.
Through increasing integration of renewable energies into the power network, this regulation also has an ever-increasing importance on the distribution network level.
Here, we likewise provide innovative system solutions. Together with conceptual design of systems for reactive power compensation and accompanying services, such as network analysis and calculation, we round out our network regulation offerings.

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.



Changes in the condition of the insulation are detected early on by MSENSE® BM. An innovative and field-tested algorithm monitors the condition of the inner conductive layers of the bushing field grading in regard to changes in capacitance (C) and dissipation factor (tan δ) and compares these changes to limit values. The key aspect of this
innovation is the 2/3 reference method: the algorithm continuously incorporates all three bushings into mutual monitoring. In addition, just only the measurement data of potential transformers on the system are required to determine the symmetry of the grid voltage.
This ensures a reliable and clear evaluation of the condition of the high-voltage bushings – regardless of network asymmetries or fluctuations in voltage.



More than 20,000 VACUTAP® VR units are currently demonstrating their value for our customers around the world. Our engineers incorporated this one-of-a-kind operating experience into the development of the new VACUTAP® VR. The result is sure to impress: Optimization of the design allowed us to increase the permitted values for step voltage and switching capacity once again.
