Insulation monitoring: The concept - Bender 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. This measuring current generates a corresponding voltage drop ...
