isolationövervakningsenhet
An isolation monitoring unit, or isolationövervakningsenhet in Swedish, is a device used to detect and alert about unintended electrical connections to earth in IT systems, also known as unearthed or floating systems. These systems are commonly found in medical electrical equipment and in industrial applications where continuous operation is critical. The primary purpose of an isolation monitoring unit is to ensure the safety of personnel and equipment by preventing dangerous fault currents from flowing to ground.
The unit works by continuously measuring the insulation resistance between the unearthed conductors of the power
