Wilhelm Peukert

from Wikipedia, the free encyclopedia

Wilhelm Peukert (born May 16, 1855 in Hodkovice nad Mohelkou (Liebenau), † April 15, 1932 in Braunschweig ) was an engineer from Bohemia .

Life

Peukert studied mathematics, physics and mechanics and in 1884 became an assistant at the Technical University in Prague . From 1885 to 1886 he held a managerial position at the Viennese cable company Franz Tobisch , at the same time as a designer at the Technical University of Vienna (now TU Vienna). In 1890 he was appointed full professor at the Technical University of Braunschweig (today TU Braunschweig) at the first electrotechnical chair and head of the institute The Electrotechnical Collection with the electrotechnical laboratory .

As an engineer, he was the assistant of Prof. Adalbert von Waltenhofen in Vienna for many years . In 1863, Waltenhofen had the experience that a soft iron rod in a coil can, under certain conditions, adopt a polarity that is opposite to the magnetizing effect. This happened when the power was suddenly interrupted. Waltenhofen had explained this anomalous magnetization with the fact that the molecular magnets swing back to their original position of rest during the interruption, exceed the equilibrium position and remain there. Gustav Heinrich Wiedemann, on the other hand, attributed this abnormal magnetization to the effect of the extra currents that occurred when the magnetizing current was suddenly opened. Peukert then tried to achieve a decision between these two explanations by means of an experiment.

Wilhelm Peukert was responsible for the entire electrotechnical training at the Technical University of Braunschweig until the First World War . This resulted in numerous research work in the field of accumulators , electrical energy technology and electrical measurement technology . The Peukert equation , which describes the charge storage capacity of an accumulator as a function of the discharge current, is named after him. For his services he was awarded the Order of Henry the Lion , in 1898 2nd class and 1900 1st class.
