Werner Hartmann was convinced that researchers need experience, patience and creativity as well as the willingness to share their ideas with as many people as possible. They also need the right working environment. And Hartmann found exactly what he needs at Siemens Corporate Technology in Erlangen, where he conducted research into vacuum switching technology and provides advice on it as a principal key expert.
This type of circuit engineering has become dominant since the 1970s, especially in the low and medium voltage areas. Practically all grid operators use it in over 80 percent of cases. But it is also expected to play an important role in tomorrow’s high voltage systems. “In our new power supply landscape, there will be far more high-voltage cables whose individual sections frequently need to be connected or disconnected,” said Hartmann confidently. In the event of a circuit failure in such a grid section, whole towns or industrial plants can suddenly be without electricity. Hartmann’s inventions help to ensure that such events will be less likely in the future.
