3. Protecting the future of networks and users
Statocompensator flicker control, which has just been discussed at length, is complex and, despite rigorous and exhaustive consideration of physical realities, the results remain modest. The characteristic shown in figure 32 shows that, for frequencies above 20 Hz, amplification rather than attenuation occurs. In industrial practice, flicker reduction in the ratio of 2.5 is very ambitious, whereas the normative requirement is often a reduction greater than three. The presence of fixed capacitors arranged as filters, with tunings on ranks three, five and two most often, is partly to blame for this modest performance. While the last tuning row of the filter introduces damping and limits the anti-resonance...

Electromagnetic compatibility
This booklet, which complements [D 4 315], [D 4 316] and [D 4 317], is intended first and foremost to give some pointers to further information, but also to situate the phenomenon of voltage fluctuations and the flicker they can cause within the large family of phenomena studied under the heading of electromagnetic compatibility...

Standardization
In the words of the IEC, slightly modified for the occasion: "All normative documents are subject to revision, and the reader is invited to seek out the possibility of applying the most recent editions of the normative documents indicated below. IEC and ISO members hold the register of International Standards currently in force".
