Due to the numerous wires on the DC side of the PV system, arc faults are more likely to occur. The figure illustrates the different types of arc faults that can occur within photovoltaic systems.
Due to the high DC voltages and the aging of the systems, long-lasting arc faults can occur which may cause serious fires. As an initial step to develop sensor-devices for detecting arc faults in photovoltaic systems, a test set-up consisting of several modules, a solar inverter, and a unit for creating artificial arc faults was installed.
The undetected grounding faults will then be contributed to parallel arc faults, but it is better to prevent them by improving the detection and protection of grounding faults. Therefore, the relevant standards and codes are mainly focused on series arc fault detection and protection in PV systems.
Typical structure of PV systems. There are mainly two types of arc faults in PV system: series and parallel (including grounding arc fault) arc fault. Parallel and grounding arc fault often draw a large amount of fault current because of the sizeable different potential, which is easier to be detected by traditional protection devices , .
aged connection box at the back side of a solar panel. An occurring arc fault might bridge this single panel. bridged by an arc fault was analyzed (fig. 1 3). instable. They d o no t last very long and are of very low energy (fig. 14).
However, the improper installation, non-frequently scheduled maintenance, and aging effect can accelerate the deterioration of PV system components, which directly increase the possibility of arc fault occurrence. The undetected arc faults pose a severe fire hazard to residential, commercial, and utility-scaled PV systems.
