Task & solution

This application describes the situation when operating an IT system, that “first fault” changes an unearthed system (IT-system) into an earthed system (TN or TT system) and that a further fault may lead to the tripping of circuit breakers and hence lead to disconnection. One fault must be monitored and give a warning and controlled switching off of the equipment. We recommend a Bender Insulation Monitoring Device. And in this document we also described the settings from this device.
