Insulation Monitoring Device IMD100
Insulation Monitoring Device IMD100 is used to ensure safe energy transmission in connections between solar power plants and electrical grids, as well as in IT networks such as those found in hospitals. It continuously monitors the insulation resistance and, in the event of a potential fault, sends a signal to open or close the circuit breaker via its integrated relays, thereby protecting the network and ensuring safe operating conditions.
