Insulation error detection system with branch-selective feed-in and selective isolation monitoring system, and method for determining a cross-link impedance between two subsystems
Insulation error detection system with branch-selective feed-in and selective isolation monitoring system, and method for determining a cross-link impedance between two subsystems
An insulation fault locating system using branch-selective feeding and a selective insulation monitoring system for a branched IT system is composed of multiple subsystems. For insulation fault location, a differential current measuring device, a test signal generator and a blocking device are arranged in each subsystem. The insulation monitoring device additionally includes a selective decoupling device arranged in each subsystem. Furthermore, a method determines a cross impedance between two subsystems on the basis of the insulation monitoring system.
