Therefore, the development of effective arc detection methods and standards is crucial for ensuring the safe and reliable operation of PV systems [11, 12]. The photovoltaic DC detection method utilizes the characteristics of arc light, arc sound, and electromagnetic radiation to monitor fault arcs in photovoltaic systems [13, 14, 15].
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 presence of series arc faults will inject extra impedance in the PV system, which can cause mismatch loss, heating loss, and decreasing fill factor. Thus, it effectively decreased the efficiency of PV system.
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.
Arc faults frequently occur in PV systems, and the sustained arc can generate high-temperature plasma that poses a significant risk of severe damage to system components [4, 5, 6]. PV DC arc damages can occur due to various reasons, including but not limited to faulty equipment, installation errors, or natural disasters.
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.
