| Abstract |
Recently, As a result of government policy to promote renewable energy sources, BIPV(Building Integrated Photo Voltaic) System replacing building finishing material with photo voltaic module has been increasing. Building integrated photo voltaic system is installed in a building by inserting a solar cell in the building finishing material. Thus BIPV systems have possibility of an electric shock accident due to decreased insulation performance because it is easy to contact human body from conductor. Especially, in case of a system using transformerless inverter system, it is structurally vulnerable to safety, so that the risk of accidents may increase. Therefore, the risk of human shock due to accidents should be studied through actual accident experiments. In this paper, as a study for the development of standards for securing human body electrical safety in BIPV system, we considered the hazard of electrical safety in the BIPV systems applied transformerless inverter and conducted analysis risk of electric shock through verification experiment. |
