Speaker:

Thomas Gsell, Technical Manager for Low Voltage Compensation at ALSTOM Grid, graduated as Power Electronics

Engineer in 1992. He founded the Jessler & Gsell GmbH, one of the world pioneer in the development and

manufacturing of Shunt Active Harmonics Filters. The company was later purchased by Nokian Capacitors which

now belongs to ALSTOM Grid. Gsell is also a lecturer at his alma mater, the University of Applied Science in

Konstanz, Germany.
