arc fault
- Thread starter abohagar
- Start date
Arcing faults in series with the load will often not trip the protecting device (breaker) because there is no high current overload. If the arc can be sustained, undetected, for long periods of time then alot of heat can build up at that fault point and cause a fire and property/life loss.
Being able to detect this incidious kind of fault is very good and is why arc-fault breakers exist.
Power line arcing is most often a problem when not in series with the load, but arcs from the line to ground through a high impedance path that adds some load to the line but does not trip any breakers.
Since arcing causes high frequency noise it can be detected and suitable action taken to correct the problem before it becomes more serious.
Good luck with your arc fault detector design.
