Abstract:

With the spread diffusion of PV system, the topics linked to the safety in all its life of these systems are everyday more and more important. In particular, the analysis of the protection systems against indirect contacts of PV generators, that differs from the distribution systems because the voltage remains on all the components of the PV plant that are upstream of the DC sectioning device (during the day) also when such a device is opened, is a very important topic on the electrical point of view.
