This standard defines and specifies the requirements and test code for dry-type and oil-immersed smoothing reactors for HVDC (high voltage direct current) power transmission. It only applies to smoothing reactors for dc transmission. It does not apply to other smoothing reactors such as reactors for power converters for variable speed drives, etc.
