Consequences of Not Having DC Arc Detection
The absence of DC arc detection can lead to severe consequences:
- Fires: Undetected arcs can sustain high temperatures, causing fires. Over 250 fires in Australia were linked to DC arc faults in PV systems (AC Solar Warehouse).
- Equipment Damage: Prolonged arcs can destroy wiring, connectors, and other components, leading to system failures.
- Safety Hazards: Undetected arcs increase risks for maintenance workers and firefighters, who may be exposed to high-voltage hazards.
- System Downtime: Arc faults can cause significant operational disruptions, requiring costly repairs.
Case studies, such as the 2009 Bakersfield and 2011 Mount Holly fires, demonstrate the severe consequences of undetected DC arcs (ResearchGate).
Consequences of Absence: Without detection, faults can go unnoticed, leading to sustained arcs that cause fires or damage. For example, over 250 fires in Australia were linked to DC arc faults in PV systems, highlighting the severe risks of undetected arcs.
