Mercury Arc Rectifier

1920s to 1990s

Saturday, March 05, 2016

Mercury Arc Rectifiers were used to convert Alternating Current (AC) power to Direct Current (DC) power. They were used by Edmonton Power starting in the 1920s until they were phased out in the 1990s.

Mercury Arc Rectifiers were used mainly to provide DC power for Edmonton's street cars and trolley buses.
