IMD 30 Insulation Monitoring Device

Insulation Monitoring devices are one of the most important equipment of IT Systems. It detects insulation faults in the system by constantly checking the insulation resistance level between phases and the earth. At the same time, it controls the load current and the temperature of the isolation transformer by the IEC 60364-7-710 standard and ensures that the warning system is started when it reaches critical values.
