High voltage direct current (HVDC) electric transmission systems will soon be operational within the United States. As this is written, it is expected that the first of these will be placed in service in late 1969 or early 1970. This marks the introduction of new stray current corrosion control problems for corrosion engineers responsible for the protection of underground metallic structures in areas traversed by the HVDC lines.
