Abstract: The electrical, mechanical, and physical requirements of oil-immersed and dry-type air core smoothing reactors for high-voltage direct current( HVDC)applications are specified. Test code is defined and appropriate technical background information is presented or identified.
Keywords: construction, dry-type air core, HVDC, oil-immersed, rating, smoothing reactors, test code application.
This standard applies only to oil-immersed and dry-type smoothing reactors for dc transmission. It does not apply to other smoothing reactors such as reactors for power converters for variable speed drives, etc

3.2 ineremental inductance: The incremental inductance of a smoothing reactor is the inductance of the smoothing reactor, in Henries, determined on the basis of a small current increase (or decrease )at a pre defined dc current. The incremental inductance is. therefore. defined as a function of dc current from the minimum current up to the maximum peak short-circuit current.
3.3 rated dc current: The rated dc current of a smoothing reactor is the maximum continuous dc current at rated conditions.
3.4 rated de voltage: The rated dc voltage of a smoothing reactor is the maximum continuous de voltage pole to ground, that will be experienced by the smoothing reactor.
3.5 ripple current: The total harmonic current content superimposed on the de current For specific engi neering purposes, it is essential to define the harmonic spectrum of the ripple current in terms of amplitude and frequency. For general purposes, the ripple current can be expressed as the root-mean-square(rms)value of the harmonic current at any level of dc current: including the continuous rated dc current.
