Insulation Monitoring devices are one of the most important equipment of IT Systems. It detects insulation fault in the system by constantly checking the insulation resistance level between phases and earth. At the same time, it controls the load current and the temperature of the isolation transformer in accordance with the IEC 60364-7-710 standard and ensures that the warning system is started when it reaches critical values.
The device, which can indicate alarm situations visually and audibly, has the feature of showing insulation fault, overload current and over temperature information of the insulation transformer both on its screen and with the LEDs on it. It also transfers this alarm information to the Remote Alarm Indicator (RAI 70) and the Local Alarm Panel (LAP 70), allowing the relevant personnel to be informed about the malfunctions.
The insulation monitoring device IMD 30 communicates with the Insulation Fault Location Device (EDS 30), allowing the authorized personnel to intervene faster with the fast detection of anyinsulation fault based on line.
