Abstract
The invention relates to a method () and to an electric circuit arrangement () for selective insulation monitoring in a power supply system () having isolable subsystems () which each has an integrated energy storage (). In this context, the subsystem to be monitored () is cyclically and temporarily isolated (S) for the duration of a measuring interval (ΔT) with all-pole semiconductor disconnectors (SW); operation of the isolated subsystem () to be monitored is continued (S) by means of its integrated energy storage () during the measuring interval (ΔT); and an insulation resistance (R) of the subsystem () is measured (S) during the measuring interval (ΔT) by means of a standard insulation monitoring device (IMD).
