Default Arc fault detection devices

RCDs are to some extent sensitive to arcing as they fail to balance
the currents correctly at the high frequencies arcs contain. AFDDs
are just RCDs/RCBOs with less hf filtering.
I read that (some?) AFDDs use microprocessors to recognise the signature
of an arc.
