Title: Innovations of Lennart Brandt in High Voltage Technology

Introduction

Lennart Brandt is a notable inventor based in Västerås, Sweden. He has made significant contributions to the field of electrical engineering, particularly in high voltage technology. His innovative approach has led to the development of a unique patent that addresses the challenges associated with high voltage plants.

Latest Patents

Lennart Brandt holds a patent for "High voltage plants with electric motors." This invention involves a plant that comprises one or more electric machines constructed with insulated conductors. These machines are connected for heavy current via insulated conductors, with the magnetic circuit in at least one of these machines connected directly to a high supply voltage ranging from 20 to 800 kV, preferably higher than 36 kV. The insulation of the electric machine is built up of a cable placed in its winding, which includes one or more current-carrying conductors surrounded by outer and inner semiconducting layers and intermediate insulating layers. The conductors may be group-wise connected in parallel, eliminating the need for semiconducting layers around every conductor in the group. If the conductors are connected in series within the group, a part insulation is required to withstand a few kV, while connection of the conductors to every phase necessitates a strong part insulation that can withstand the phase voltage of the high-voltage supply network.
