Insulation Monitoring

Insulation monitors, or IMDs (Insulation Monitoring Devices), play a critical role in safeguarding unearthed AC, AC/DC, and DC power supplies within IT systems. They continuously assess insulation resistance, ensuring it meets safety standards by comparing it to earth. Mandated by the “Safety of Machinery” standard, insulation monitoring devices are indispensable for accident prevention, fault detection, and fire protection in IT systems.
