Fault location methods integrated into the instrument

Method Principle
Sauty Location of broken wire: With measurement of loop resistance, if Rab > 10 000 Ω, the wire is broken
Test on homogeneous cables
Murray Location of insulation fault: If Ihealthy > 1000, Iunhealthy (ou Ib > 1000 Ia)
Test on homogeneous and heterogeneous cables
Fabe / Küpfmüller Location of insulation fault: If Ihealthy/ Iunhealthy > 2 x Rhealthy/Runhealthy, Ih+Iu > 1000 Rab, Ihealthy and Iunhealthy
Test on homogeneous and heterogeneous cables
