    Abstract - (Show below) - (Hide below)

    Defines the requirements for insulation monitoring devices (IMD) which permanently monitor the insulation resistance R[F] to earth of unearthed a.c. IT systems, of a.c. IT systems with galvanically connected d.c. circuits having nominal voltages up to 1000 V a.c., as well as of unearthed d.c. IT systems with voltages up to 1500 V d.c. independent from the method of measuring.
