WebThe general three stage assessment approach has remained, in line with G5/4 (and G5/3), but has now been expanded to provide multiple sub-stages. The intention of this is to simplify the assessment process for new connections, although the process now appears more complicated at first glance. Most of the harmonic limits (for planning and ... WebDo we need to consider harmonics up to (or beyond) 100th harmonic as this seems to be implied by ENA EREC G5/5? Yes we do for new installations as per the new G5/5. There may be derogations applicable to installations that predate G5/5 as I believe G5/4-1 only looked at orders up to the 50th.
