2) "Harmonic suppression guideline for specific consumers"
This guideline sets forth the maximum values of harmonic currents outgoing from a
high-voltage or specially high-voltage consumer who will install, add or renew
harmonic generating equipment. If any of the maximum values is exceeded, this
guideline requires that consumer to take certain suppression measures.
