How do arc-faults affect PV bankability and safety? How arc-faults and fires have the power to influence public perception. Technical solutions for arc-faults - Chris Oberhauser Texas Instruments arc-fault detection method and product description. Pros/cons of this approach: cost vs. arc-fault isolation.
One of the greatest risks to any person maintaining an electrical production facility is arc flash. Arc flash risk is eliminated by de-energizing equipment when it is being worked on. However, it has become more common to maintain solar plants while they are still energized.
An arc fault in a solar system occurs when an electrical current jumps across a gap between two conductive surfaces, creating a brief but intense burst of heat and light. This can happen when there is damage or wear to electrical wiring, connectors, or other components in a solar PV system, creating a pathway for the current to arc.
UL report of firefighter safety & Photovoltaic system (CESA. Another potential risk is if a firefighter must open the roof in order to access the PV system. This means cutting through live conductors, an action that almost always creates an arc and can constitute a significant and dangerous shock hazard.
