Enhancing Performance of Filament Cage Metal Oxide Surge Arresters: MV & HV Applications

Mr. Hippler received his BSc degree in 2010 and started his career as project engineer for HIGHVOLT Prüftechnik Dresden in the field of high voltage measurement equipment. He obtained an MSc at the Brandenburg University of Technology Cottbus, Germany in 2013, graduating in the field of high voltage technologies. Currently, he works in research of high voltage surge arresters at the Ilmenau University of Technology and since 2016 also works for Tridelta Meidensha’s R&D department.

The Uc of a metal oxide arrester is one of the most important design criteria since good protection can only be achieved if the arrester is not electrically, thermally or mechanically overloaded. This presentation reports on research contributing to dimensioning and selection of filament cage type MO arresters and presents a measuring system to determine electrical conductivity and power loss density of MO varistors with a DC voltage and one or more superimposed AC voltages with different frequencies.
