 HVDC Lehrte–Misburg

HVDC Lehrte–Misburg was an experimental high-voltage direct current transmission line between Hannover-Misburg and Lehrte-Ahlten substation.It was designed by Erwin Otto Marx and served to assess the reliability of its components in continuous service, namely the converters which were based on arc discharges in air in contrast to other projects which use mercury vapour rectifiers.
