- This part of IEC 61557 specifies the requirements for insulation fault location systems which localize insulation faults in any part of the system in unearthed IT a.c. systems and unearthed IT a.c. systems with galvanically connected d.c. circuits having nominal voltages up to 1 000 V a.c.@ as well as in unearthed IT d.c. systems with voltages up to 1 500 V d.c.@ independent of the measuring principle. NOTE 1 IT systems are described in IEC 60364-4-41 amongst other literature. Additional data for a selection of devices in other standards should be noted. NOTE 2 Further information on insulation fault location can be found in the following standards: IEC 60364-4-41:2005@ 411.6@ and IEC 60364-5-53:2001@ 531.3
