Abstract
In large-scale photovoltaic systems, it is not appropriate to use a conventional insulation monitor, since its test pulse is damped too much by the number and length of the feed lines. According to an embodiment of the invention, a remedy is provided here in that the photovoltaic system is subdivided through circuit design into multiple subsystems that are electrically insulated from one another, and the test pulse is transmitted to the connecting line associated with the applicable subsystem in sequential order. According to a second embodiment, the behavior of the current of the test pulse through the connecting lines is sensed by current sensors and evaluated in an analysis unit.
