Original and Brand New BAILEY Module 3BHB007211R102 XVC768102
Description
The concept of earthing applied to a photovoltaic (PV) system may involve both the exposed conductive parts (e.g. metal frame of the panels) as well as the generation power system (live parts of the PV system e.g. the cells). A PV system can be earthed only if it is galvanically separated (e.g. by means of a transformer) from the electrical network by means of a transformer. A PV insulated system could seem apparently safer for the people touching a live part; as a matter of fact, the insulation resistance to earth of the live parts is not infinite and then person is passed through by a current returning through such resistance. This current rises when the voltage to earth of the plant and the plant size increase since the insulation resistance to earth decreases. Besides, the physiological decay of the insulators, due to the passage of time and the presence of humidity, reduces the insulation resistance itself. Consequently, in very big plants, the current passing through a person in touch with the live part may cause electrocution and therefore the advantage over the earthed systems is present only in case of small plants.
