Insulation monitoring function Insulation fault location The insulation monitoring device continuously monitors the entire insulation resistance of an IT system during operation and triggers an alarm when the value falls below a preset response value. To obtain a measurement the device has to be connected between the IT system (unearthed system) and the protective earth conductor (PE). A measuring current in the μA range is superimposed onto the system which is recorded and evaluated by a microprocessor-controlled measuring circuit. The measuring time is dependent on the selected...

ISOloop Ring systems are a special type of coupled systems in which all systems can be coupled to form a ring interconnection. The ISOloop function ensures that, in a system with several insulation monitoring devices, one device is always actively measuring. The devices that work in an ISOloop configuration are combined into a group. Within the group, digital inputs are used to control which devices are currently working together in a team. Within the team, the device with the lowest BCOM address takes over the measuring task. The basis of the ISOloop function is the combination of several...
