43. 太陽電池アレイの直流感電リスクに関する基本実験

抄録

In this paper, aiming at active discussion on electrical shock caused by PV module string/array, several basic measurements concerning this accident were carried out by using actual PV module string/array. As result, following information were obtained: (1) human body current might be affected by not insulation resistance measured by insulation tester but some unknown lower resistance component, (2) human body current is in proportion to the square of series number of PV module, and (3) blocking diode is ineffective for protection of electrical shock.
