  • Insulation monitoring: The concept - Bender

    Operating principle of an insulation monitoring device. The insulation monitoring device is connected between the live supply conductors and earth and superimposes a measuring voltage U m. In the event of an insulation fault, the insulation fault R F closes the measuring circuit between the system and earth, generating a measuring current I m that is proportional to the insulation fault.
