VDE Art. No.: 0100779
This standard applies to devices responsible for the detection and to devices for detection and interruption of electric d.c. arcs in photovoltaic systems. The standard covers the testing of arc detection and response times of interruption devices used for serial arcs within PV circuits The standard defines reference scenarios according to which the testing shall be conducted. This standard covers mechanisms connected to systems not exceeding a maximum PV source circuit voltage of 1500 V d.c. The equipment may also be connected to systems not exceeding 1000 V a.c. at the a.c. main circuits, non-main a.c. load circuits, and to other d.c. source or load circuits such as batteries but not ensuring arc fault detection in these circuits.
