considered when establishing the human body protection standards in case of DC ground fault
accidents.
In addition, experiments with changes in electrical continuity showed that in all cases where the
human body is significantly wet, the electrical continuity value is greater than 0.5 Ω, causing a fatal
electrical current to flow to the human body. In the case of a normal condition, an accident current that
could have an effect on the human body is flowing if the electrical continuity value is greater than 30
Ω. If electrical continuity is less than 0.2 Ω, it is believed that contact of the BIPV frame and all
extraneous conductive parts with both hands will not have a serious effect on the human body in a
flooded environment, but a further study will be needed because depending on the installed capacity
of the actual BIPV the current value of the human body may change.
Therefore, to protect the human body according to the construction of the BIPV, it must be
considered that the human body is protected from electric shock by applying auxiliary equipotential
bonding and additional protective control facilities to the extraneous conductive parts that may consist
of closed circuits. Also, the human body must be fully protected from accidents in the event of electric
shock due to insulation accident through regular inspection and proper maintenance to maintain low
electrical continuity.
