Isolations overvågning

Unplanned standstills of machines and systems as a result of insulation errors can have serious consequences. By detecting such errors in ungrounded networks (IT networks) early on, DOLD insulation monitors prevent outages of electrical systems and thus guarantee higher operating and system security. The system operator is informed early on about pending critical operating conditions and people and machinery are protected by the insulation monitoring. The functionality of DOLD insulation monitoring devices has been intentionally designed simply. You profit twice over from this: through high user-friendliness as well as cost savings.
