On mission: The troubleshooter.

Anyone working for a company with global expertise in voltage regulation is going to be on the move quite a bit. And even at his home location in Regensburg, Uwe Seltsam has a large area of operation: field work, customer meetings, technology meetings. As a group manager in troubleshooting, his daily work takes him from the office to technical departments and from putting on a suit to pulling on some overalls and back again. All with the goal of solving problems. Ideally, before they even happen. A degree in electrical engineering and many years at MR give him the knowledge and skills to accomplish this.

Mission: The 600,000 dollar job.

The glowing hot metal starts to cool off as a cellphone rings at one in the morning at Reinhausen, 7,000 kilometers away. The report of a failure comes as a surprise.
Every minute counts from here on out. Especially when a steel mill is sitting idle on the other side of the globe. Our service team moves heaven and earth. A short time later, our specialist is already sitting on a plane. His destination: Canada. There is no time for jet lag once he's there. The problem is resolved quickly. When the next shift starts, it is as if there had never been a failure. Our customer's thanks is the only reminder of what transpired. 

Service: Premium.

The company that builds the best tap changers in the world can only offer one kind of service: the best. This is not just evidenced by our unconditional commitment to service calls around the world, but through a "Premium Service Provider" seal of approval. And the regular training, theoretical and practical testing and thousands of service calls per year that that entails. This is how we ensure uniform quality and service using state-of-the-art technology. No matter whether in Canada, Africa or New Zealand.

In action: The pioneer.

Anyone working in an innovative company with global competence in voltage regulation recognizes and promotes opportunities for the future before anyone else. As the manager of the business division Power Distribution, Ansgar Hinz is thus making a crucial contribution to the energy turnaround, together with his team. Using the technology of adjustable local network transformers (RONT), he is helping to significantly increase the carrying capacity of distribution networks for renewable energies. His business activities are perfectly orchestrated, from the presentation of technology and execution planning to the technical planning of the system, as well as installation and commissioning. He’s helped in this not only by his training as a church musician, but also his studies in Electrical Engineering and 18 successful years at MR.

Project: Future.

The houses glow in a deep, surreal red light. Shortly after, their rooftops start to glisten and sparkle. A sunrise that seems to come from the future. As the solar cells deploy their full power, the RONT really gets going. MR’s adjustable local network transformer (RONT) can manage all the voltage fluctuations perfectly, without additional cables having to be laid. Good news for the residents. And good for the environment, because it’s not just the Wörnitz that flows through Larrieden, but also any amount of clean energy.

Technology: GRIDCON® with MR RONT.

A local network station that ensures the economic integration of renewable energies – that’s GRIDCON® by MR. In its interior, the adjustable local network transformer RONT ensures stable voltage at all times. And as usual with MR, one innovation leads to another. The project in Larrieden was thus the forerunner of a new product line: GRIDCON®, an important building block for the energy turnaround.

In action: Mrs. Cool.

Karin Rothenstein sends tap-changers to Siberia and to the desert. However, she places high demands on herself as well as on our products. She configures test and measuring equipment, and evaluates data precisely. She supports our tap-changers from the sample stage through to the start of production. She has scrutinized almost every MR product in this manner. A dedication that pays off at MR – in future, she will be working as a speaker for General Management.

Order: Tests, Tests, Tests.

The thermometer in the temperature chamber is showing -60° C. The insulating oil is as viscous as honey. At these temperatures, a person would be unable to move within a very short space of time. Despite this, the on-load tap-changer completes one step operation after the next as precisely as Swiss clockwork. The door to the cold chamber opens, and a frosty mist rises up the twelve-meter-high roof of the test center, which is unique worldwide. Clothed in thickly padded protective suits, two assembly operators push the tap-changer out of the simulated Siberia. But that’s not the end of the ordeal. After a heat test at 130° C, it will be struck by an artificial bolt of lightning with 1.5 million volts. But it copes with that as well, before proving its mechanical prowess in the time lapse test. Later, it will need to operate for at least another 50 years or more without failure. A requirement that our technology meets with at all times.
