This article deals with the determination of the lifetime of electrolytic capacitors operating in industrial DC micro grids, which are characterized by a particular large number of electrical drives. In addition to the advantages of such a DC grid, a test setup is proposed as a solution that allows an easy device testing. The paper shows with the help of simulations and practical measurements that if every device passes this test, it can be ensured that no capacitor in the DC grid is overloaded at all.
