This part of IEC 60214<\/span> <\/span> applies to on-load tap-changers of both resistor and reactor types, de-energized tap-changers, and their motor-drive mechanisms.<\/p>\n

It applies mainly to tap-changers immersed in mineral insulating oil according to IEC 60296<\/span> <\/span> but may also be used for tap-changers with air or gas insulation or immersed in other insulating liquids insofar as conditions are applicable.<\/p>\n

It applies mainly to tap-changers with arcing contacts but may also be used for arcing-free on-load tap-changers (such as electronic switching) insofar as conditions are applicable.<\/p>\n

This part of IEC 60214<\/span> <\/span> applies to power and distribution transformers of all types and also to reactors.<\/p>\n

It does not apply to transformers and reactors mounted on railway rolling stock.<\/p>\n
