Applicable to oil-immersed three-phase and single-phase convertor transformers for use in HVDC power transmission.

This part of IEC 61378 applies to oil-immersed three-phase and -single-phase convertor transformers for use in HVDC power transmission. It applies to transformers having two, three or multiple windings. This standard does not apply to convertor transformers for industrial applications (see IEC 61378-1) and to convertor transformers for traction applications (see IEC 60310).
