Aandrijftechniek/transportbandtechniek betrouwbaar bewaken
Moderne installaties bevatten steeds vaker elektromotoren of pompen die met softstarters of frequentieomvormers worden aangedreven. Deze genereren echter kritische harmonische verstoringen in de AC-netvoeding. Reguliere RCD's of eenvoudige isolatiemonitoren (bijv. de 3-lampenmethode of het 2-voltmeterproces) beveiligen deze processen niet correct. Verder moet rekening worden gehouden met lekstromen en de belasting van de isolatie van de motoren. Er is moderne bewakingsapparatuur van Bender nodig om deze problemen snel te detecteren en te melden.
