Tap-changers – Part 1: Performance requirements and test methods
|Publication Date:||1 May 2014|
|ICS Code (Transformers. Reactors):||29.180|
This part of IEC 60214 applies to on-load tap-changers of both resistor and reactor types, deenergized tap-changers, and their motor-drive mechanisms.
It applies mainly to tap-changers immersed in mineral insulating oil according to IEC 60296 but may also be used for tap-changers with air or gas insulation or immersed in other insulating liquids insofar as conditions are applicable.
It applies mainly to tap-changers with arcing contacts but may also be used for arcing-free onload tap-changers (such as electronic switching) insofar as conditions are applicable.
This part of IEC 60214 applies to power and distribution transformers of all types and also to reactors.
It does not apply to transformers and reactors mounted on railway rolling stock.
